SU369565A1 - DEVICE FOR CALCULATION OF FUNCTION y = e ^ - Google Patents

Description

one

The proposed device relates to the field of computer technology and can be used to calculate dependencies using number-pulse codes.

Devices for calculating functions are known that contain counters, counters, registers, and logic circuits.

The disadvantage of such devices is their complexity.

The purpose of the invention is to reduce the equipment for calculating dependencies using number-pulse codes.

This goal is achieved by the fact that the output of the assembly circuit is connected to the younger section of the counter-register.

The scheme of the proposed device shown in the drawing.

The device contains a counter /, a counter-register 2, a prohibition scheme 3, an assembly scheme 4.

The device works as follows.

Input 5 receives a pulse number code

Р „T 2

where FO is the pulse frequency at the input; T is the conversion time; n is the number of bits in the counter.

Depending on the code received in the counter-register 2, the frequency of the pulses at point 6 will be equal to:
