1. The problem statement, all variables and given/known data x(t) = 3*sin(1000*pi*t) Suppose that the signal is sampled at a rate of fs = 2000Hz. What is the discrete time signal obtained after sampling (i.e., the signal expressed as a function of sample number n, x[n]) What discrete time frequency, f-hat will the signal x[n] be at if x(t) is sampled at its nyquist frequency? 2. Relevant equations From the previous parts of this problem: Original Frequency in hertz: 500 Hz Niquist frequency: 1000 Hz 3. The attempt at a solution I do not understand what a discrete time signal is, and as such, i have no idea what to do for these two steps of the problem.
