lab2-conv
This does convolution of two sequences in stepwise manner according to normal understanding.
sigfold.m:-fips signal 1..and changes n accordingly.
sigshift.m:-shifts flipped signal from left to right to cover all overlapping
sigmulti.m:-multiplies two signals at each instant of overlapping
convolution.m:-it finally calculates the sum of the product
