Analysis and synthesis of signals using complex zeros
thesis
posted on 2018-08-15, 08:39 authored by M.H. AckroydThis thesis reports studies based on the concept of
characterising a band-limited signal by the locations of its zeros
In a ‘complex time’ plane (whose real axis is the real variable t). The relations between the zeros of a signal and more conventional
descriptors such as Nyquist samples, Fourier coefficients or
spectral samples are investigated.
Added noise or linear filtering changes the zeros of a
signal in a complicated way. The problems which arise are discussed.
Signals can be synthesised directly from a specified zero
pattern. The properties of signals having a certain class of zero
pattern (‘angle coded signals’) are studied. A method is presented
by which zero patterns can be produced which yield signals (suitable
for radar use) having desired properties. [Continues.]
