DIGITAL SIGNAL PROCESSING-Introduction Questions & Answers

DIGITAL SIGNAL PROCESSING-Introduction Questions & Answers ADC - CORRECT ANSWER - produces a stream of binary numbers from analog signals. Aliasing - CORRECT ANSWER - an effect that causes different continuous signal to become indistinguishable when sampled. Analog Signal Processing - CORRECT ANSWER - vary continuously in time and amplitude, processed using electrical networks containing active and passive elements. antialiasing pre filter - CORRECT ANSWER - signal must be pre-filtered by a low pass filter. ASP block diagram - CORRECT ANSWER - Function > Sampler > Quantizer > Coder > binary numbers Bandlimited - CORRECT ANSWER - The signal x(t) must be ___________, that is, its frequency spectrum must be limited to contain frequencies up to some maximum frequency, fmax, and no frequencies beyond that. Coding - CORRECT ANSWER - The coding process in A/D converter assigns a unique binary number to each quantized levels Digital signal processing - CORRECT ANSWER - - processing of digital signals. - signals can also be processed using digital hardware containing adders, multipliers, and logic elements, or using special-purpose microprocessors.
