<p>The receiver control arrangement with a pulse generator is controlled by pulse counts whose frequency is proportional to the supply frequency. The arrangement produces a step pulse after receiving a predetermined number of input pulses. The step pulses are received by output selectors for further processing. Such arrangement can be extended to include several counters which can be series or parallel connected with first outlet of generator and each cam issue a step impulse after receipt of a preset number of input pulses. The arrangement comprises also :- 'OR' gates, a decoder, delay stages and a filter.</p> |
