Specify the aliasing frequency of a signal that has a maximum
frequency of 92kHz and a sample frequency of 130kHz. Is this an
optimal sampling frequency? If so, explain why? If not, propose an
optimal sampling frequency.

If signal x(t) has a maximum frequency (wm1)and signal y(t) has
a maximum frequency (wm2)where wm2>wm1, determine the Nyquist
rate for each of the following signals:
(a)x(t)+ x(t-1)
(b) dx/dt
c) x(t)y(t)
(d)x(t)*y(t)
A signal with a maximum frequency of 3 kHz is sampled at 50
kHz. What would the required transition width be in Hertz
to...
(a) decimate the signal by a factor of 8? (b) decimate the signal
by a factor of 5? (c) interpolate the signal by a factor of
4?
Assuming that audible sound has a maximum frequency of 10000 Hz,
what is the maximum number of radio channels that can fit onto the
FM radio band without overlap? (The frequency range of FM is 88 MHz
to 108 MHz).

1- Aliasing can affect DFTs, where higher frequency signals can
appear as lower frequency signals due to the use of an N point DFT
that has a limit to the highest frequency it can detect. Give one
approach when using a DFT to reduce the potential of aliasing.
2-. When using the standard MATLAB commands, or the
design equations, to design an FIR filter why is it a good idea to
check if the design meets requirements ? Be specific....
