Filtering in the frequency domain:

Industrial Engineering Dept.

University of Parma – Italy

Could be better operate in the frequency domain

Problems

• Filtering can be performed only when all data are available

• Order of FFT is too high.

x(n)

X(k)

FFT

X(k) · H(k)

Y(k)

y(n)

IFFT

x(n) Ä h(n)

y(n)

Solution

• Overlap & Save algorithm.
