Patent MX-9704827-A (MX)
Title: Digital fm demodulator.
Inventor: LAROSA CHRISTOPHER P
IPC: H03D3/00
Filed: 1997-06-26
Abstract: In the digital FM demodulator (330), a hard limiter (333) receives a modulated analog IF signal and limits the voltage of the IF signal to two levels. Next, a direct phase digitizer (360) uses zero-crossings of the limited IF signal to generate N-bit digital words. A phase differential circuit (340) computes the phase sift of the signal from the direct phase digitizer over a predetermined time interval. The dynamic range of the phase differential signal can be increased by replacing the phase differential circuit (340) with a high-resolution phase differential circuit (700). After digital demodulation and filtering and gain control by audio processor (360), the recovered signal is forwarded to a speaker (390) to produce an audio output. Thus, the digital FM demodulator both avoids problems common to analog discriminator circuitry and offers a reduced complexity, size, and power consumption alternative to conventional digital FM demodulators.
