Communication satellites orbit Earth and provide global coverage for telephone calls and television, as predicted by Arthur C. Clarke in 1945. The U.S. launched the first communication satellite in 1945, proving the concept successful. Satellites receive signals shot from cameras and transmit them to set top box companies to be viewed on televisions. Communication satellites are important today, helping provide service to distant and remote areas while aiding defense, phone calls, and signal transmission, though they are expensive and can experience networking problems.

Can "Smart Homes" change the future of how older adults live?
Smart homes that incorporate emerging technologies have the potential to help older adults live independently for longer by providing remote monitoring, safety alerts, and assistance with daily tasks. However, there are still concerns about security, adoption rates, and the high costs associated with implementing smart home technologies on a large scale. Researchers are exploring new prototypes like mobile medical homes that could be placed on a caregiver's property to help address these issues and support aging in place.
Introduction to AM modulation
1) Amplitude modulation (AM) varies the amplitude of a carrier wave according to the amplitude of a modulating signal. This generates sideband frequencies above and below the carrier frequency.
2) The sidebands are softer than the carrier and produce an effect like overtones or subtones, making them useful for timbre construction. More complex modulating signals produce more sidebands.
3) In an example where a 1,000 Hz carrier is modulated by a 100 Hz signal, the results are signals at 1,000 Hz (the carrier) as well as 1,100 Hz and 900 Hz (the upper and lower sidebands).
Analog to analog conversion - Amplitude modulation
why we need analog to analog conversion.
key terms - modulation - bandpass - band pass filter
types of conversion
amplitude modulation
Amplitude modulation
Analog modulation involves representing analog information as an analog signal. It is needed when the transmission medium is bandpass in nature or only a bandpass channel is available. There are three main types of analog modulation: amplitude modulation (AM), which changes the amplitude of the carrier signal; frequency modulation (FM), which changes the frequency; and phase modulation (PM), which changes the phase. AM encodes the modulating signal as variations in the envelope of the carrier signal. This results in a spectrum with the carrier frequency flanked by upper and lower sidebands. The bandwidth required is twice that of the modulating signal.
Amplitude shift keying
Amplitude shift keying (ASK) is a digital modulation technique that represents binary data by changing the amplitude of a carrier wave. In binary ASK (BASK), also known as on-off keying (OOK), a high amplitude represents a binary 1 and a low or off amplitude represents a binary 0. The demodulator determines the amplitude of the received signal to recover the original data. ASK transmitters and receivers have a simple design but the transmission is susceptible to noise. ASK is used in early telephone modems and transmitting digital data over optical fibers.
Lec am modulation
Modulation involves modifying a carrier signal with a modulating signal to make it suitable for transmission. There are two main types of modulation: analog and digital. Analog modulation includes amplitude modulation (AM), where the amplitude of the carrier wave varies with the modulating signal. AM can take different forms such as double sideband suppressed carrier (DSBSC) and single sideband (SSB) to improve power and bandwidth efficiency.
Pulse amplitude modulation (PAM)
Pulse-amplitude modulation (PAM) encodes message information in the amplitude of signal pulses. A PAM-4 modulator takes two bits at a time and maps them to one of four amplitude levels, such as -3V, -1V, 1V, and 3V. Demodulation detects the amplitude level of each symbol period. PAM is widely used for baseband digital data transmission, though other modulation methods are now more common.
Amplitude modulation
Amplitude modulation (AM) is a modulation technique where the amplitude of a carrier wave is varied in proportion to that of the message signal being transmitted. In AM, the amplitude of the carrier wave is modulated by the instantaneous amplitude of the lower frequency modulating signal. This results in a modulated wave whose amplitude varies in accordance with the modulating signal. The carrier frequency remains unchanged in AM. Demodulation of AM signals can be done using envelope detection or synchronous detection methods. Envelope detection is simpler but introduces more distortion, while synchronous detection is more complex but introduces less distortion.

It provides equations, diagrams, and explanations for DSBAM, SSBAM, and synchronous demodulation. Key aspects covered include the carrier signal, message signal, sidebands, modulation depth, spectrum analysis, and transmitter power efficiency comparisons between DSBAM and SSBAM.
Optical satellite communication

It is compact in size at 200x200x150mm and has the potential to enable high-capacity intersatellite links with advantages over microwave technologies in terms of mass and power consumption.
Amplitude shift keying (ask)
Amplitude Shift Keying (ASK) is a modulation technique where the amplitude of a carrier signal is varied according to the amplitude levels of a digital signal. In ASK, a digital signal of 1s and 0s is multiplied with a carrier signal, with a 1 having no effect on the carrier signal but a 0 reducing the carrier signal amplitude to zero. ASK has high efficiency and low noise interference but also high bandwidth and power consumption, making it suitable for applications like satellite links.
Amplitude modulation
1) Modulation involves changing characteristics of a high-frequency carrier signal according to an information signal. This allows signal transmission over long distances and multiple signals over the same channel.
2) The main modulation types are amplitude modulation (AM), which changes amplitude; frequency modulation (FM), which changes frequency; and phase modulation (PM), which changes phase.
3) AM is the simplest form and varies the carrier amplitude by the information signal. It has advantages of simplicity but is inefficient in power and bandwidth usage, and susceptible to noise.

This document discusses satellite communication, including what satellites are, how satellite communication systems work, different types of satellite orbits, the evolution of satellite technology from passive to active satellites, services provided by satellites such as television and radio broadcasting, advantages of satellite communication such as its universal and reliable coverage, and applications such as military and internet access. The future of satellite communication is discussed, with expectations that satellites will have more onboard processing capabilities and power to handle higher bandwidth demands.
Introduction to satellite communication
Satellite communication allows people to communicate across long distances. Arthur C. Clarke first proposed the idea of communication satellites in 1945. The first satellite launched was Sputnik 1 by Russia in 1957, though it did not have communication capabilities. Commercial satellite communication began with the launch of Early Bird in 1965. Satellites can be in low, medium or geostationary orbits and operate in different frequency bands like C-band and Ku-band. They provide advantages like global coverage and reliability over terrestrial networks.

This document discusses the evolution of nanosatellites and CubeSats. It begins with a brief history of early satellites from Sputnik 1 to Vanguard 1. The CubeSat standard was then developed in 1999, defining small satellite sizes and interfaces to allow universities to design and build complete small satellites. Since 2013, commercial companies have launched large constellations of CubeSats for applications like Earth observation and weather monitoring. The CubeSat standard continues to evolve with larger form factors being developed and defined.
History on cell phones
The history of cell phones began in the 1920s with the emergence of radio communication technologies. The first mobile phone call was made in 1946 in Sweden using a handheld radio connected to the telephone network. Through the 1940s and 1960s, cell phone technology evolved with developments like mobile car phones and cell towers that divided coverage areas and enabled two-way communication.
