Abstract
This paper analyzes and compares signal processing of the four absolute value circuits, namely, bridge rectifier chip DBI04S, the precision full -wave rectifier circuit of traditional diode using the chip LM358, clamping amplifier full - wave rectifier based on the AD8037, single power and full - wave rectifier utilizing the chip AD822. In conditions of frequency at 2kHz and 10kHz, respectively, it analyzes the precision of every circuit's output signal compared with the added signal source, and gets the best processing approach of rectifier circuits. By analysis and comparing, single power and full -wave rectifier utilizing the chip AD822 get the best effects finally.关键词
