Digital Signal Processing - Binary Test with
QUESTIONS and 100% Correct Answers
Digital-to-analog converter (DAC) - ✔✔a circuit used to convert the digital representation of
an analog signal back to the analog signal
DSP - ✔✔digital signal processor; a type of microprocessor that processes data in real time
Execute - ✔✔a process of computer or DSP pipeline operation in which the decoded
instructions are carried out
fetch - ✔✔a process of computer or DSP pipeline operation in which an instruction is
obtained from the program memory
Nyquist frequency - ✔✔the frequency that specifies the limit of the analog frequency to be
sampled and defines it to be one-half of the sampling frequency
pipeline - ✔✔part of DSP architecture that allows multiple instructions to be processed
simultaneously
quantization - ✔✔the process whereby a binary code is assigned to each sampled value
during analog-to-digital conversion
sampling - ✔✔the process of taking a sufficient number of discrete values at points on a
waveform that will define the shape of the waveform
aliasing - ✔✔the effect created when a signal is sampled at less than twice the Nyquist
frequency. Aliasing creates unwanted frequencies that interfere with the signal frequency
