Transient Response and Phase Equalization in Magnetic Recorders
Because of editing, balancing and other operations, magnetic recordings ultimately released by major studios may be many generations separated from the original recordings. Irregularities in transient response and generation of cross-modulation distortion have not been commonly specified performance criteria in magnetic recorders. Nevertheless, these may detrimentally affect a multiple generation recording. The generation of phase and cross-modulation distortion is explained in detail and solid state circuit techniques for reducing them are analyzed. Examples of circuitry, waveform performance and test procedures are presented.
