ABSTRACT:
A cue signal detection circuit including a CTL head for reading a reproduction control signal recorded on a magnetic tape, an amplification circuit for converting a reproduction control signal into a digital signal, a filter unit for converting a digital signal into an analog voltage corresponding to a duty ratio of the signal, a frequency-dividing circuit for generating a timing signal in accordance with the operation of a capstan motor, and an analog-to-digital conversion circuit and a determination circuit for taking in a voltage value of a reproduction control signal converted into an analog voltage in response to a timing signal to detect a cue signal from among reproduction control signals based on the taken in voltage value.
