Digital Signal Processing – Finals Questions & Answers Convolution - CORRECT ANSWER - A mathematical operation which expresses input and output relation of an LTI system Convolution - CORRECT ANSWER - Provides impulse response of an LTI system and input relation to their output Convolution - CORRECT ANSWER - Without this, we cannot see clearly the relationship between the input and output Discrete System - CORRECT ANSWER - Classified into linear and non-linear systems Discrete Time Fourier Transform (DTFT) - CORRECT ANSWER - Decompose at time domain signal into a series of trigonometric or exponential functions components of frequency Discrete Time Fourier Transform (DTFT) - CORRECT ANSWER - You need ___________ to convert time-domain to frequency-domain signal DSP - CORRECT ANSWER - System processes an input signal into an output signal Impulse Response - CORRECT ANSWER - It modifies the signal of the LTI system, used to filter the signal. Thus, it can make a high pass or low pass filter Input-Output - CORRECT ANSWER - In Linear Time Invariant, the _____________ relationship does not vary with time when signal shifted advance or delay..
