摘要： A remote control arrangement uses pulse code modulation for transmission as in infrared remote control arrangements. A feature of the arrangement is that only one quartz oscillator is necessary and is used in the receiver part. The receiver measures the first pulse width transmitted and, dependent on that, defines the measured period of a control circuit. A primary feature is that the arrangement is provided with a prepulse having a threefold pulse width before the start pulse thereby allowing the preamplifier of the receiver to be in its normal operating area when the start pulse occurs.

摘要： The invention discloses a method and apparatus for digitally generating a variable pulse train with some pulses in a period T, the number of which can be changed step by step. The pulse train can be used for generating a variable dc voltage particularly for the tuning voltage of TV receiver capacitance diodes.
