Classify each of the following as
either true or false.
(a) In the FIR design using the window
method, side lobes appear due to numerical round-
off
errors
(b) The DC gain of the transfer
function H(z) = is 0.4
- FIR Filters have all zeros at the origin.
- IIR (recursive) Filters can never be unstable
- Windows are used in FIR Filter design to reduce the size of
side lobes in the frequency response.
- A causal Filter will always have a proper z-transfer
function
- For a Filter to be stable, all its zeros must be inside the
unit circle.
- FIR Filters have the advantage of generally requiring less
memory than recursive (IIR) Filters.
- The aliasing phenomenon occurs in both continuous time Filters
and discrete time Filters.
- For a stable discrete time Filter, the discrete transfer
function poles are always in the left half plane.
