How to convert signal z(n) to z(t) mathematically?

  1. Aug 9, 2011 #1
    i have a signal y(t).I have sampled my signal at T0,so i got y(nT0).I multiply this signal with a random number r uniformly distributed in the range 0.95-1.05.Now z(t)=r*y(nT0).How to get z(t) mathematically?

    Welcome to PhysicsForums!

    Are you're asking how to take a Z transform, given that you have discrete points, or are you asking how to interpolate your signal and form a continuous signal from the discrete data points that you have?
