In this presentation we discuss about a particular type of analog communication waves that is wideband frequency modulation. In this slide, its expression is discussed along with graphical visuals. Not forgetting its power and bandwidth as well. We also see the use of bessel function and the block diagrams that help to form this type of waves.

Salient Features:
The magnitude response is nearly constant(equal to 1) at lower frequencies
There are no ripples in passband and stop band
The maximum gain occurs at Ω=0 and it is H(Ω)=1
The magnitude response is monotonically decreasing
As the order of the filter ‘N’ increases, the response of the filter is more close to the ideal response
Design and implementation of qpsk modulator using digital subcarrierGongadi Nagaraju
The digitally implemented QPSK modulator is developed for satellite communication for future satellite missions. As we know that for space application power and bandwidth are most important parameters.The size of PCB and component count are also important parameters. To reduce these all parameters we design new approach. The new approach also minimizes the component count and hence reduces the PCB size. In this modulator summation, orthogonal sub-carrier generation and mixing of subcarrier with data are all digitally implemented inside the FPGA

this ppt only for beginner who want to understand concept of Timer counter operation of LPC2148 step by step.
hope it may help u.
always welcoming ur suggestion.
This presentation gives the details about the data types available in Embedded C. It also discusses the pros and cons of writing codes in C for 8051. Different example codes are considered.
Frequency-Shift Keying, also known as FSK is a type of digital frequency modulation. It is also often called as binary frequency shift keying or BFSK
Similar to analog FM, it is a constant-amplitude angle modulation.
This presentation will discuss the concepts behind FSK

Where the wild things are - Benchmarking and Micro-OptimisationsMatt Warren
You don’t want to prematurely optimise, but sometimes you want to optimise, the question is - where to start? Profiling and Benchmarking can help you figure out what your application is doing and where performance problems could arise - allowing you to find (and fix!) them before your customers do.
If you aren’t already benchmarking your code this talk will offer some starting points. We’ll look at how to accurately benchmark in .NET and things to avoid. Along the way we’ll also discover some surprising code optimisations!

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.
