Abstract : A PAM tester using a shift register generated sequence and a conventional data (PCM) bit synchronizer and detector for synchronization was investigated. It was found to function satisfactorily with and without predetection tape recording. This tester can be implemented by adding digital-to-analog converters (DAC's), an error gate, and a rms voltmeter to a PN PCM tester which uses a shift register to generate the PN sequence. (Author)
