Non recursive filters


I. The output sample Sk is a function of:

  1. present and past inputs (En and En-i)
  2. past outputs (Sn-i) only
  3. present input (En) and past outputs (Sn-i)


II. What is the relation between the filter coefficients Ai and the values of the impulse response Hi?

  1. Ai = Hi
  2. Ai = 2*Hi
  3. Ai = Hi/2


III. The non recursive filters are:

  1. Always stable
  2. Never stable
  3. Astable


IV. Give the method for non recursive filter design:

  1. Poles and zeros method
  2. Bilinear transform
  3. Windowing
