Energising circuit for reproduction unit for tuning receiver - has inverter input circuit for changing signal to one of two switching states

摘要

The energising circuit is for a reproduction module which can be used for tuning a radio or TV receiver or similar instruments. The module contains an AD converter which changes the input signal into two sets of digital codes. The digital signals are used to energise the reproduction elements. The module has a signal inverter input (8) for the changeover signal, which can be in a number of switching states. In one of the switch-over states, each signal amplitude of the input signal corresponds to a reproduction pattern where a max. of one of the reproduction elements is energised.
