    • A process is disclosed for converting standard musical notes to natural musical notes based upon Rod formats. A signal of standard musical notes is input and the frequency of each note in the signal is analyzed. A Rod format natural harmonic resonance is selected and the frequency of each note in the signal is converted to a natural frequency corresponding to the selected Rod format natural harmonic resonance. A signal consisting of the converted notes is output. An apparatus capable of performing the inventive process on a signal of standard musical notes includes a signal input port and a signal output port, means for converting the frequency of standard musical notes to a corresponding natural frequency corresponding to a Rod format, means for selecting a Rod format natural harmonic resonance, and a frequency analyzer.

    • A front-end circuit according to the present invention includes a VCO which oscillates a local signal, a mixer which converts an RF signal Frf into a baseband signal, a DC offset cancel circuit which detects a DC offset contained in the baseband signal and then eliminates the DC offset, and a local frequency control circuit which controls a frequency of the local signal. In a case where the RF signal is an analog television signal, the local frequency control circuit controls the frequency of the local signal so that a frequency of the baseband signal differs from each frequency spectrum of a luminance signal contained in a video signal which is generated by demodulating the baseband signal. This makes it possible to provide the front-end circuit which can prevent video distortion caused when a frequency spectrum is eliminated from the luminance signal.
