Digital Signal Processing Questions & Answers

Digital Signal Processing Questions & Answers Aliasing error - CORRECT ANSWER - distortion of the digital signal caused by a sampling rate that is too low in relationship to the highest frequency of the input signal sample represents a much lower frequency analog filter - CORRECT ANSWER - used to limit and shape the bandwidth of the signal before it is digitized and to filter out distortion after the signal has been converted back to an analog signal consist of electronic circuits built from resistors, capacitors, and inductor that affect continuous signals and modify them in the time and frequency domains antialiasing and anti-imaging filters analog signal - CORRECT ANSWER - a continuos signal analog signal processing - CORRECT ANSWER - ASP alternating current electrical signals are directly modified by changing their temporal and spectral properties via the use of electronic components like capacitors and inductors analog-to-digital converter - CORRECT ANSWER - ADC converts analog signal to digital signal anti-imaging filter - CORRECT ANSWER - protects against imaging errors low-pass filter used at output of DAC antialiasing filter - CORRECT ANSWER - low-pass filter before ADDC to remove frequencies higher than the Nyquist frequency binary code - CORRECT ANSWER - al signals represented by 0 or 1 indicates a stream of changes between two states of a given physical variable like voltage or current bit - CORRECT ANSWER - each available space where a 0 or 1 must appear smallest amount of info that can be processed by binary computers yes-no question
