Referring to Computer Example 3.4, draw the block diagram of the system represented by the simulation loop, and label the inputs and outputs of the various loop components with the names used in the simulation code. Using this block diagram, verify that the simulation program is correct. What are the sources of error in the simulation program?
EXAMPLE 3.4
The preceding example demonstrated the required amplitude response of the VSB filter. We now consider the phase response. Assume that the VSB filter has the following amplitude and phase responses for f > 0:
