Question
Suppose x(t) = 5 cos (2 t f t) where f=10KHZ.
1. By hand
Find the discrete-time signal x[n] when sampling frequency is
O fs = 50 KHz
O fs = 100 KHz
Find the quantized signal xq[n] signal (fs=50 KHz). Use 8-level quantization with range
of 10 volts.
2. Write a MATLAB *.m file to find the discrete-time and quantized signals when fs = 50
KHz. Draw the signals: original continuous-time signal, discrete-time signal, and
quantized signal.
