发明名称 Ground loop injection VHF tuner
摘要 A VHF tuner circuit comprising an oscillator for generating a harmonic which is close to the RF frequency, including resonant circuit means for providing a low impedance path for coupling the desired harmonic current to the mixer and for providing a high impedance path for all the other harmonics, thereby suppressing the reception of spurious signals.
