Different ADC architectures are introduced such as serial ADCs, successive approximation ADCs, and pipeline ADCs. Specific circuit implementations and operating principles are outlined for single-slope, dual-slope, and successive approximation ADCs.
An octal to binary encoder is a digital circuit that takes an octal (base-8) number as input on 8 lines and outputs the corresponding 3-bit binary number. It works by using a truth table and logical expressions to relate each octal digit to a combination of the 3 binary output lines, allowing conversion from octal to binary. The encoder is implemented as a circuit using logic gates to perform this conversion physically.
C++ was developed by Bjarne Stroustrup as an extension of C with object-oriented features like classes. It allows access to most C features and headers but some C features are not advisable for security reasons. C++ code is generally faster and more lightweight than other high-level languages. It supports multiple versions and can target any platform but does not have automatic garbage collection. C++/CLI was introduced by Microsoft and allows using both native C++ and CLI syntax. Popular development tools for C++ include g++, Visual Studio, and Mingw compilers.
1) A phase-locked loop (PLL) is a control system that generates an output signal whose phase is related to the phase of an input signal, allowing it to synchronize signals or generate a frequency that is a multiple of the input frequency.
2) In a simple PLL, a phase detector (PD) converts the phase difference between the input and a voltage-controlled oscillator (VCO) output to a voltage, which changes the VCO frequency to follow the input.
3) Ripple in the control voltage to the VCO can produce side bands, so a low-pass filter is used to fix this voltage ripple problem and improve stability.

Millimeter wave 5G antennas for smartphonesPei-Che Chang
This document describes research on millimeter-wave antennas for 5G smartphones. It discusses several antenna designs for both 60 GHz and 28 GHz applications. For 60 GHz, a 2012 design integrated a 16-element phased array directly into a printed circuit board. Later designs in 2013 and 2017 explored integrating antenna arrays with reconfigurable polarization into mobile device chassis. A 2014 design proposed a 28 GHz mesh-grid patch antenna array for 5G cellular devices, demonstrating an 11 dBi gain array integrated into a Samsung phone. The document outlines various antenna designs, simulation and measurement results to enable millimeter-wave smartphone connectivity.
1) The document discusses the modulation techniques used in various Global Navigation Satellite Systems (GNSS), including GPS, Glonass, BeiDou, and Galileo.
2) GPS uses BPSK-R modulation with a 2.046 MHz bandwidth. Glonass uses FDMA, while the others use CDMA.
3) BOC modulation, used in Galileo, modulates the signal with a subcarrier signal that can be either sine or cosine. This results in a spectral distribution around the subcarrier frequency.
Rainfall intensity duration frequency curve statistical analysis and modeling...bijceesjournal
Using data from 41 years in Patna’ India’ the study’s goal is to analyze the trends of how often it rains on a weekly, seasonal, and annual basis (1981−2020). First, utilizing the intensity-duration-frequency (IDF) curve and the relationship by statistically analyzing rainfall’ the historical rainfall data set for Patna’ India’ during a 41 year period (1981−2020), was evaluated for its quality. Changes in the hydrologic cycle as a result of increased greenhouse gas emissions are expected to induce variations in the intensity, length, and frequency of precipitation events. One strategy to lessen vulnerability is to quantify probable changes and adapt to them. Techniques such as log-normal, normal, and Gumbel are used (EV-I). Distributions were created with durations of 1, 2, 3, 6, and 24 h and return times of 2, 5, 10, 25, and 100 years. There were also mathematical correlations discovered between rainfall and recurrence interval.
Findings: Based on findings, the Gumbel approach produced the highest intensity values, whereas the other approaches produced values that were close to each other. The data indicates that 461.9 mm of rain fell during the monsoon season’s 301st week. However, it was found that the 29th week had the greatest average rainfall, 92.6 mm. With 952.6 mm on average, the monsoon season saw the highest rainfall. Calculations revealed that the yearly rainfall averaged 1171.1 mm. Using Weibull’s method, the study was subsequently expanded to examine rainfall distribution at different recurrence intervals of 2, 5, 10, and 25 years. Rainfall and recurrence interval mathematical correlations were also developed. Further regression analysis revealed that short wave irrigation, wind direction, wind speed, pressure, relative humidity, and temperature all had a substantial influence on rainfall.
Originality and value: The results of the rainfall IDF curves can provide useful information to policymakers in making appropriate decisions in managing and minimizing floods in the study area.

Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.
