BASIC Java Socket is a java class which have features to share texts, files, mails and any types of data between two different PC (connected by cable) or in localhost. In this tutorial I have shown how to transfer file…
BASIC FCFS stands for First Come First Serve. The simplest scheduling algorithm. First come first serve scheduling algorithm states that the process that requests the CPU first is allocated the CPU first. It is implemented by using the FIFO queue.…
BASIC Windows reduces DFT leakage by minimizing the magnitude of the function. There are four types of windows. They are, Rectangular Window Triangular Window Hanning Window Hamming Window Rectangular Window w(n) =1; for n=0,1,2,…………………………N-1 Triangular Window w(n) = n/(N/2); for…
BASIC In signal processing, the Z-transform converts a discrete-time signal, which is a sequence of real or complex numbers, into a complex frequency-domain representation. Z-transform of x(n) is given by, MATLAB CODE In z-transform we find a function always that includes…
BASIC The discrete Fourier transform (DFT) converts a finite sequence of equally-spaced samples of a function into a same-length sequence of equally-spaced samples of the discrete-time Fourier transform (DTFT), which is a complex-valued function of frequency. DFT of x(n) is defined by, MATLAB CODE To evaluate a DFT code…
BASIC Correlation or is a measure of similarity/ relationship between two signals. If x[n] & h[n] are two discrete-time signals, then the correlation of x[n] with respect to h[n] is given by, Correlation mathematically is just Convolution with the second…
BASIC Convolution is the process by which an input interacts with an LTI system to produce an output. Convolution of an input signal x[n] with a system having impulse response h[n] is given by, TABLE METHOD Table method to find…
BASIC Frequency Modulation (AM) is a one of the conventional modulation technique to transmit signals using a carrier wave. The frequency of a high frequency carrier wave is changed in accordance with the frequency of message signal. In frequency modulation…
BASIC Amplitude modulation (AM) is a one of the conventional modulation technique to transmit signals using a carrier wave. The amplitude or the strength of a high frequency carrier wave is changed in accordance with the amplitude of message signal.…
Basic High Density Bipoler 3 Zero (HDB3) works in a similar way to AMI by changing poles for each binary 1. Moreover when it found 4 consecutive 0’s it replace them by ‘000V’ or ‘B00V’ depending on number of non-zero…
