に記載の衛星放送用受信機。[Claims for Utility Model Registration] (1) A tuner that receives a satellite broadcasting signal, a second intermediate frequency amplifier that amplifies the received signal,
A bandpass filter that removes noise components from the amplified signal, an AGC detection circuit that generates a DC voltage according to the signal level that has passed through the bandpass filter, and an audio level display circuit and switch that displays the audio level. A satellite broadcast receiver comprising a switch, which switches an audio level display circuit to display an AGC voltage which is an output of the AGC detection circuit, and uses this as a reception level display of a satellite broadcast signal. (2) Claim (1) in which the audio level display circuit of a VTR is used as the audio level display circuit.
Satellite broadcasting receiver described in .
