    • PROBLEM TO BE SOLVED: To provide a method and a circuit for effectively suppressing an interference signal.
      SOLUTION: A TV signal converted into an intermediate frequency is demodulated into an in-phase signal (I) by an I/Q demodulator in order to suppress interference signals from adjacent TV channels, and demodulated into an orthogonal signal (Q) using a signal shifted in phase by a phase angle π/2 relative to the signal. The in-phase signal (I) is filtered by a first Hilbert of a Hilbert filter pair having an even symmetrical impulse response. The orthogonal signal (Q) is filtered by a second Hilbert filter of the Hilbert filter pair having a ununiform symmetrical impulse response. The Hilbert-filtered orthogonal signal (Q) is added to the in-phase signal (I) by an adder 21 in order to obtain a video output signal (SVideo). The Hilbert-filtered orthogonal signal (Q) is subtracted from the in-phase signal (I) by a subtractor in order to obtain a sound output signal (SSound).

    • PROBLEM TO BE SOLVED: To provide a method and a circuit device for measuring frequency differences of carrier waves in demodulating a received symbol in a phasor space composed of complex numbers in quadrature modulation method (QAM), in which the received symbol for frequency measure is compared with a symbol on a target position in a complex signal space. SOLUTION: It is proposed that angles (∠(P1, P2)) between two received signal values (P1, P2) are measured and compared with a target angle which enables quadrature modulation method in order to make measurement irrelevant to the rotation of coordination system of received signal corresponding to a coordination system of symbol. The angle deflection between a specific angle and a target angle of the received signal values can be used as a direct measure for a frequency deviation (Δf). COPYRIGHT: (C)2006,JPO&NCIPI
