Abstract:
A system for analyzing the performance of a tape recorder having a record input and a playback head providing an output thereof, said system comprising:(a) a signal generator that repeatedly generates a predetermined waveform for a predetermined duration which is routed to the record input of the tape recorder;(b) an analog-to-digital converter receiving the output of the playback head and providing a corresponding digital signal thereof;(c) a digital signal processor that receives the digital signal and converts it into digital data representative of elementary components thereof; and(d) means for receiving and analyzing the digital data to determine the performance of the tape recorder, said means for analyzing digital data comprising:(i) means for determining the fundamental frequency of data said repeatedly generated said predetermined waveform;(ii) means for determining the average of said repeatedly generated said predetermined waveform; and(iii) means for determining the harmonic frequencies of said repeatedly generated said predetermined waveform.
