Abstract
The concept of sampling is central to the operation of
all systems in which analog information is to be processed
by a digital computer. In conventional hybrid
computing and data-processing systems the continuous
analog signal is represented by an amplitude-modulated
pulse train in which the pulses occur at fixed intervals of
time. Such synchronous sampling facilitates control by
the digital computer clock and requires a minimum
amount of equipment. In many applications, however,
it is important to minimize the number of samples employed
to represent the analog signal. For example in
telemeter applications, it is important to economize
transmitter power by limiting the number of samples
transmitted over long communication links.
