A high performance receiver with graphic displays and a synchronous detector

Abstract

A recently developed SW receiver can not only receive conventional broadcasting clearly, but also demodulate and print out facsimile signals. Moreover, the LCD display provides receiving conditions and status. Three technologies, i.e. a high precision PLL synthesizer (10 Hz resolution), a new demodulating circuit and a 8-bit microcomputer control with large memory size support the above mentioned functions.<>
