A waveform-preserving, variable time-delay system capable of
several milliseconds delay is described in this thesis. These considerably
long delays are achieved by judicious use of the relatively
low sonic velocity of gases. Initial system design criteria specified
a time delay of ten milliseconds and a signal bandwidth of 0-10 KC....
The derivation of coefficients for the transfer functions of maximally flat time-delay networks generally begins from an infinite
series approximation of the ideal transfer function. This thesis presents two alternative methods that are particularly suited to cases
involving an unequal number of poles and zeroes in the transfer function. The...
In the first part of this thesis,
two new classes of rational approximations to the ideal delay function
based on the Khovanskii continued fraction expansion of e[superscript]x
are studied in detail in both the frequency domain and the time domain and comparisons
with other delay
approximations (by Budak, Allemendou
and...
