MATLAB Code for Sampling Theorem and effect of under sampling

WebAug 31, 2024 · Traditional radar imaging can be realized by matched filtering the received signal of the uniformly arranged array. However, compared with the uniform array radar, the sparse array radar’s spatial sampling is not uniform; thus, the signal does not satisfy the Nyquist sampling theorem in the azimuth direction so it cannot be processed by DFT. WebJan 22, 2024 · Nyquist Frequency is the highest frequency, therefore this nyquist frequency gets doubled to get the nyquist rate. This nyquist rate then gets multiplied by 5 to get the sampling frequency and finally is divided over one to get the sampling period(1/F = T). The code below shows perfectly how I followed this process. WebNov 30, 2024 · Algorithm: 1. Input the desired frequency fd (for which sampling theorem is to be verified). 2.

WebMar 25, 2011 · All of us, dealing with signal processing are familiar with the Nyquist–Shannon sampling theorem. According to it, in order to achieve proper sampling (and avoid aliasing) the sampling frequency must be at least two times the bandwidth of a bandlimited signal. WebMay 29, 2024 · As an example suppose that my functions are sin(x) and cos(x). The first approach is using the conv() command in MATLAB. The second approach is to calculate it directly using the definition of convolution. The third method is using the convolution theorem and calculating it using fft() and ifft(). The code is attached here.
