tailieunhanh - Lecture Signals, systems & inference – Lecture 2: Transforms

The following will be discussed in this chapter: DT convolution to z-transform (and system function), DT convolution to DTFT (and frequency response), using frequency response to specify response to sinusoidal inputs, frequency response (DTFT of unit sample response),. | Signals Systems Inference Lec 2 Transforms 1 DT convolution to z-transform and system function o y n J h k x n k k o x n z0 all n z 0 X y n h k z0 Z0 k o H Z0 2 DT convolution to DTFT and frequency response o y n J h k x n k k o x n ejQ n all n and n Qo n y n jQ k ejQ n 0 h k e k o 3 H ej Q
