Digital signal processing question:
![1. Consider the STDTFT defined as jwk where n] is the speech signal and wIn] is the window sequence. Prove the following properties a. Linearity -if n]-ax[n]+by[n], then V(o,n)-aX(o,n)+bY(o,n b. Shifting-ifYn]=x(n-n] , then V(a,n)-X(a,n-nen, c. Modulation _ ifv[n] =x(n em, , then l(?,n)=X(?-o,,n). d. Show that can be put in the form ie. X(a,n) is a smoothed spectral estimate of X(?) at frequency ?,](http://img.homeworklib.com/questions/89ce1a50-b89d-11eb-a197-6783bce76728.png?x-oss-process=image/resize,w_560)
