I want to design a simple Low pass filter with equiripple window function and cut off freq at 200 hz . Could somebody please help me how to design low pass filter for below code?
clc; clear all; close all; t=1:0.01:5; x=2*sin(1000*t)+2*sin(500*t); subplot(4,1,1); plot(t,x); fs=2000; nfft=length(x);...

Do we need to sample a analog signal before taking FFT for it in MATLAB?
Consider y=sin(t), I want to take the FFT for it.Can I take the FFT for it without sampling? Is that the right way?
