Can somebody explain the steps in finding the DTFT of a signal x[n]? I want to know about the final formula too. I've seen it as like :
a(1 - r^n/1 - r)
How does that become the final form?

Can somebody please explain the difference between the catalytic triads of trypsin and chemotrypsin? I know that chemotrypsin is a Ser protease while trypsin is an Asp protease but what does that mean more specifically. I tried looking up structures for both of the triads and found that they both contain Ser195, His57 and Asp102 and they are connected in the same manner too. I am really confused between the differences, please help. Thank you

DFT can also be obtained using matrix multiplication. Let X[r] show the transformed values and x[n] show the original signal. Using the analysis equation: Using matrix multiplication, this operation can be written as x[O X[1 1 e(2m/N) e-K4n/N) x12] [N-1]] e-j(2(N-1)T/N)e-j(4(N-1)m/N) Instead of huilt-in EFT function use matrix multinlication to solve 3th auestion [ 1 e-/(2(N-1)(N-1)T/N)]Le[N-1] DFT is an extension of DTFT in which frequency is discretized to a finite...

I am confused as to some properties of solving for DFT and DTFT. I am given a series of x[n] values and have to determine the X[k]. The formula for R[k] is sum[x(n)cos(2pi*k*n/N)], which make sense. However, when I plug the values (1, -1, 1, -1) into the equation, I get zeros across the board. Matlab tell me that at k=2, R[2] should be 4, but the only way that make sense is if the summation is an alternating series....
