Abstract

The invention provides a hardware implementation signal amplitude adjusting system, and belongs to the technical field of electronics. The system is composed of an upper computer, a parameter communication module, an amplitude modulation factor analysis module, a factor symbolization module, a signed signal shifting module, a signed bit multiplication module, a signed bit addition module and a DACmodule. An amplitude modulation factor is set in a digital mode to change the numerical value of a digital signal with sign bits, so the effect of adjusting the analog signal output amplitude of theDAC module is achieved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a signal amplitude adjustment system realized by hardware. Background technique [0002] Signal amplitude adjustment plays an important role in signal transmission and processing. The signal receiving end has certain requirements on the signal amplitude or the receiving end needs to adjust the signal amplitude to stimulate the subsequent circuit. A method with adjustable signal amplitude, wide adjustment range and high adjustment accuracy came into being. [0003] DAC is a digital-to-analog converter, a module that converts digital signals to analog signals. [0004] Independent DAC chips generally have two types of chips, serial and parallel. For example, DAC0832 belongs to the parallel control port; DAC7612 belongs to the serial input port. The serial port includes serial port, I2C, SPI, etc. Parallel port is generally 8 or 16 bits. For example, DAC0832 belongs to 8-bi...
