Digital Signal Processing - Ch.2
questions and answers already
graded A+(GUARANTEED
SUCCESS)
Periodic Sampling - answer the process of representing a continuous
signal with a sequence of discrete data values.
folding frequency - answer an important quantity in sampling theory and
is referred to by different names in the literature, such as critical Nyquist,
half Nyquist, and folding frequency.f(sub)s/2
band-limited signal - answer any signal energy outside the range of +- B
Hz is below the sensitivity of the system.
Nyquist Criterion - answer the very important relationship of f(sub) s is
greater than or equal to 2B
Bandpass sampling - answer to sample a continuous bandpass signal that
is centered about some frequency other than zero Hz.
Benefits of bandpass sampling - answer 1-reduces the speed requirement
of A/D converters below that necessary with traditional lowpass sampling
2- reduces the amount of digital memory necessary to capture a given
time interval of a continuous signal.
frequency translation - answer The process of moving a signal from one
part of the frequency axis, to another part of the axis.
Sampling translation - answer Bandpass sampling performs digitization
and frequency translation in a single process.
