摘要： In a receiver, a synchronization circuit (MIX2, OSC, C1, R1) provides a set of oscillator signals (OSI, OSQ) that are synchronized with a carrier of an amplitude-modulated signal. The set of oscillator signals (OSI, OSQ) comprises a quadrature oscillator signal (OSQ), which is substantially 90° phase shifted with respect to the carrier of the amplitude- modulated signal. A quadrature mixer (MIX2) mixes the quadrature oscillator signal (OSQ) with the amplitude-modulated signal so as to obtain a quadrature mixer output signal (MO2a). A phase-error corrector (PEC) adjusts the phase of the oscillator signals in response to a variation in the magnitude of an alternating current component (AC) in the quadrature mixer output signal (MO2a).

摘要： To demodulate a quadrature input signal (Si) (for example, frequency shift) a demodulation unit ( DEM ) is used, comprising a PLL ( P ) having a complex mixer (M) and a controlled oscillator (V). Normally, a limiter has to be used to keep the loop gain independent of the amplitude of the quadrature input signal. In the PLL, a divider (DEL) is coupled between the mixer (M) and the oscillator (V) to divide the two mixed components (Sm1, Sm2) of the quadrature signal supplied by the mixer.

摘要： A cost effective digital stereo decoder (216) for Digitized Intermediate Frequency (DIF) FM radio receiver (100). After FM demodulation (212), a multiplex signal (MPX) at a high sampling rate is mixed with free-running local quadrature mixers (308, 320) to shift the (L-R) stereo signal to baseband. The MPX signal is also mixed with a free-running locally generated carrier signal to translate an embedded 19KHz pilot tone signal to 1KHz. The pilot tone signal is decimated to a low sampling rate to permit a phase-lock loop (PLL) to be applied to the lower rate signal to estimate the phase of the pilot signal. An FM blender controller is used to attenuate high frequency noise and improve audio quality. The receiver may be implemented in software and be customer configurable to have various operating characteristics.
