H03K2005/00071 - CPC Classification

Classification description:

Manipulating of pulses not covered by one of the other main groups of this subclass; Delay, i.e. output pulse is delayed after input pulse and pulse length of output pulse is dependent on pulse length of input pulse; Variable delay controlled by a digital setting by adding capacitance as a load
