Doublet detector for data recording or transmission |
摘要 |
A data recovery circuit useful in magnetic data recording systems employs doublet pulses to at least partially encode data. Measurement of the slope of the transition between doublet pulse half-cycle peaks and of the amplitude of this transition allows rejection of high frequency low amplitude noise and high amplitude low frequency noise. The use of nearly the entire peak-to-peak voltage swing of doublet pulses makes identifying them relatively reliable.
