摘要: A television receiver is arranged to selectively display either information from a broadcast signal or an auxiliary video signal, in accordance with the position of switching network which signals are capacitively coupled via respective capacitors. Similar black reference levels established for and by means clamping circuits, including coupling capacitors, operate at different times but respect same voltage.
