Algebra Linear Equations

This is a simple way of expressing non-linear scales (such as decibels) in python. In stead of:gain = 10 ** (12/10.)Use

wen we give the two sequence ,we will get the o/p of linear convolution.the two sequences are computing by particular formula.thus we will got the output from the two sequences. the impulse response also we will get.
