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.
