Abstract

PURPOSE:To achieve excellent FM demodulation, by corresponding the change in pulse width based on the change in a counter output selected at a counter output selection signal generating circuit, into the change in the count number, in an FM demodulation of a magnetic recording/reproducing device. CONSTITUTION:A delay time of conversion from high to low level of the output of an FF10 in response to clock pulses is almost the same as the delay time when the output of the FF10 is converted into low to high level at the next clock pulse. Thus, the ratio of the output pulse width TOUT1 of the FF10 in response to n1-count to the output pulse width TOUT2 of the FF10 in response to n2-count is n1/n2. Then, the DC level of an analog signal can be kept almost constant even if the reproduction speed is changed.
