Abstract:
1. A digital/analog common tuner that can receive both a first television signal modulated digitally and a second television signal modulated analogically, comprising: a frequency conversion circuit frequency-converting an input signal into an intermediate frequency signal; a digital demodulation processing circuit converting a first intermediate frequency signal that is said first television signal frequency-converted by said frequency conversion circuit into a digital signal and demodulating said digital signal; and an analog demodulation processing circuit demodulating a second intermediate frequency signal that is said second television signal frequency-converted by said frequency conversion circuit, wherein said frequency conversion circuit and said analog demodulation processing circuit are accommodated in a cabinet that functions as electromagnetic shielding, whereby the digital demodulation processing circuit is excluded from the electromagnetic shielding cabinet.
