Abstract
A digital decoder for Miller encoded signals is disclosed comprising a resettable counter which is clocked at a frequency which is a large multiple of the base frequency of the Miller encoded signal. Transitions in the Miller encoded data stream are used to reset the counter. Digital signal storage means are provided for storing a digital signal having a value substantially equal to the value to which the counter is advanced in one Miller unit of time. Output logic circuit means responsive to outputs from the counter and digital signal storage means produces a binary output signal indicative of the decoded Miller encoded input signal. Means are provided for recurrently updating the contents of the digital signal storage means to adjust for variations in the base frequency of the Miller encoded input signal.
