A method of function generation is discussed based on the use of hybrid digital
analogue techniques.
A brief description of a quantizer is given together with some experimental
results. The purpose of this unit is to give the derivative with respect to time
(in quantized form) of a variable. Units of this type used in conjunction with
pulse modulators, which are also described, are shown to be capable of performing
a wide variety of analytic functions. The application to correlation functions, using
magnetic core storage for time delays, is also discussed.
Another application is a fast analogue/digital converter with an incremental bit
resolution time of one micro-second.
The possibility of extending the application to generation of arbitrary functions of
one or more variable is considered and one possible form of instrumentation, based
on the use of magnetic core storage, is described. |
