Title: Improvements in or relating to pulse interval discriminating arrangements
Inventor: FENTON ROGER WAKEFIELD
IPC: H04N5/46
Filed: 1963-02-21
Abstract: 1,007,672. Electrical testing. MARCONI CO.Ltd. Dec. 2, 1963 [Feb. 21, 1963], No. 6954/63. Heading G1U. An arrangement for distinguishing between two regular pulse trains having different pulse intervals, eg. for differentiating between line pulse signals derived from television signals on 405 and 625 line standards comprises a transistor monostable multivibrator circuit T1, T2 which is adjusted to remain in it unstable state for a period equal to half the interval between successive pulses of the pulse train having the larger interval between pulses and a relay having opposed winding RA, RB connected in the collector circuits of the transistors. The transistors alternately conduct for equal periods when the circuit is switched by 405 line pulses applied via capacitor C1 and the relay remains unoperated. Application of 625 line pulses reduces the time interval during which the circuit remains in its stable state and the resultant unbalance of the collector currents in the relay windings energizes the relay.
