Abstract
A pseudo vertical synchronizing signal producing circuit produces a pseudo vertical synchronizing signal which is used instead of a regular vertical synchronizing signal of a video signal during a special reproduction mode of a helical scan type magnetic recording and/or reproducing apparatus. The pseudo vertical synchronizing signal producing circuit effectively utilizes a counter circuit for producing a pulse when a counted value therein reaches predetermined threshold values set therein, and employs a minimum number of monostable multivibrators and external variable resistors coupled thereto, so that the circuit can easily be manufactured in the form of an integrated circuit.
