Question:
Duplicate Example 16.3, but for 64 points sampled at a rate of Δt = 0.01 s from the function
f (t) = cos[2 π (12.5)t] + cos[2 π (25)t]
Use fft to generate a DFT of these values and plot the results.
Example 16.3
Transcribed Image Text:
Computing the DFT of a Simple Sinusoid with MATLAB Problem Statement. Apply the MATLAB fft function to determine the discrete Fourier transform for a simple sinusoid: f(t) = 5+ cos(2л (12.5)t) + sin(2л (18.75)) Generate 8 equispaced points with At = 0.02 s. Plot the result versus frequency.
