Unformatted text preview: nts the filter in direct form; note that this command does not compute the transient part of the output corresponding to the end of the input signal. To plot a DT signal in MATLAB you can use the stem command (e.g., stem(y) generates a stem plot of the vector y).) 3. Suppose we have a CT signal s( t ) whose Fourier Transform S ( f ) is shown below: a. b. c. d. € € e. € € Find s( t ) Let x c ( t ) = s( t ) cos(20000 π t ) . Find and plot X c ( f ) . What is the Nyquist rate for sampling the signal x c ( t ) ? Suppose that x c ( t ) is sampled at a rate of 20 kHz (that i...
