Total Difference-Frequency Distortion: Practical Measurements

Document Thumbnail

A practical distortion meter using modern digital and analog integrated circuits has been designed to measure IEC total difference-frequency distortion (TDFD). the low noise and residuals of this instrument permit measurements down to one part per million (0.0001%) of distortion for signal levels of only 1 V peak to peak. The fully in-band TDFD test is simple, rapid, sensitive, and stringent, enabling informative results to be obtained on all classes of equipment. Sample measurements are presented for amplifiers, preamplifiers, open-reel and cassette tape recorders, a digital recording adapter, and a loudspeaker.
