I am using filtering to find the system response of a linear difference equation, y[n+1]-1.01y[n]=x[n+1]. The input will be x[n] = 500u[n]-1500delta[n-4]. Delta is an impulse function. I am not sure how to set up the inline function (4th line from bottom) to handle the delta term, -1500delta[n+1]. Are the coefficients,... 7 Mar 2010 12:56
