Abstract
In an image intermediate-frequency processing apparatus, in addition to a first phase locked loop (PLL) for receiving a television broadcast, there is provided a second PLL including a voltage controlled oscillator (VCO), two frequency-dividing units, a reference signal generating unit, a phase-comparing unit, and a filter. When receiving FM broadcast, a stable oscillation output obtained from the VCO is input into an audio intermediate frequency detector, to obtain an audio signal of high quality.
