1 KHz Synchronous Detector using AVR microcontroller
Downloads: Assembler source deco030511C.asm AVR Studio hex file is deco030511C.hex Overview This circuit employs a synchronous demodulator to separate a 1 KHz signal from noise and measures the amplitude of the 1 kHz signals once a second at about 60 microvolts per count then sends the measurements via an RS-232 interface for further […]
