Consider the signal f(t) = 5sin(2pi(261)t) + sin(2pi(277)t).
a) Compute and plot the magnitude of the DFT for f(t) using "fftshift", assuming a sampling rate of 8000 Hz and a duration of 0.5 second.
b) Window the samples of f(t) using a hann window then compute and plot the magnitude of the DFT using "fftshift" for the windowed data.
Design a circuit with output f and inputs x1, x0, y1, and y0. Let X=x1x0 and Y=y1y0 represent two 2-digit binary numbers. The output f should be 1 if the numbers represented by X and Y satisfies X>=Y
