A Tape-Recorder, Transient-Response Equalizer

摘要

The theory and operation of a simple phase equalizer that will correct much of the phase or delay distortion produced by instrumentation and audio tape recorders is described. This distortion degrades the pulse response by providing different time delays for various frequency components of a pulse or transient waveform. Compensation has also been provided for sag and ringing on rectangular waveforms. This adjustable equalizer has been designed to be used on the playback output of directrecord tape recorders. Operation of the equalizer is described in the appendix, which may be used as an operation manual. (Author)
