Audio automatically compressed circuit diagram

Published:2012/12/20 2:37:00 Author:Ecco | Keyword: Audio, automatically compressed

This simple automatic audio compression circuit uses direct regulation technology to control amplitude of the output signal. In contrast, the common feedback technique is used to adjust the input signal. In many audio applications, it's important to have a constant level for the audio signal. This is a real circuit specifically for speech modulated radio transmission applications. The speech circuit is also often applied to the intercom or telephone system. This the sound adjustment cost price is not very expensive. The circuit design here uses simple and inexpensive material.   (View)

4 ~ 20mA temperature transmitter circuit using voltage output integrated temperature sensor

Published:2012/12/20 2:11:00 Author:Ecco | Keyword: 4 ~ 20mA, temperature transmitter , voltage output, integrated temperature sensor

The circuit can convert TMP35 output voltage signal into a standard 4 ~ 20mA current signal for the Automation Instrumentation and industrial temperature control. It uses 4mA as zero-scale value, 20mA as full scale value. REF193 is the 3V reference voltage source, OP193 is an op amp. RP1, RP2 are respectively calibrate full scale and zero potentiometers, the two can be adjusted independently by each other. The VD1 is an Schottky diode, it can prevent the rising of OP193 open loop voltage. The Supply Voltage is available in the range of +9 ~ +18 V.   (View)
