Abstract

PURPOSE:To make unnecessary the use of especially expensive diodes, by the series connection of a diode detecting the signal in UHF band and picking up video signal and another diode detecting the video signal to pick up the peak value. CONSTITUTION:Television broadcast waves in UHF or SHF band are detected with the 1st diode 5 to pick up the video signal. Further, this video signal is detected with the 2nd diode 6 to pick up the peak value. Thus, the 1st diode 5 need not to be peak detection, but a diode detecting signals, and since the 2nd diode 6 rectifies the video signal as it is, conventional diodes can be used for it.
