Figure 1 shows the FSK demodulation circuitry in which neither PLLs nor high-quality-factor bandpass filters are used. With this high-frequency (HF) demodulation circuit, no trimming adjustments ...

To derive the transfer function of thequadrature demodulator, the phase shift network is first drawn as asmall-signal circuit model (Figure 2). The impedance(Z p) of the parallel combination of L,R p, ...

This article investigates the demodulation capabilities of a DSSSsuper-regenerative receiver. Starting from the general expressionthat characterizes the receiver's behavior, we demonstrate that afew ...

How partial dynamic reconfiguration helped make an FSK demodulator - October 3, 2012: Fabio Giovagnini and Antonio Di Marzo, SESM S.C.A.R.L. EETimes (10/2/2012 5:54 PM EDT) Partial dynamic ...

The figure shows a block diagram of the command and data handling block developed in-house to implement the telemetry and telecommand functionality necessary on the satellite. In the process, various ...

After no success they moved to a hardware solution in the form of the XR-2211 FSK Demodulator chip. It should have been simple, feed it the signals and read the digital output pins to capture the ...

A 1200bit/s FSK demodulator interface provides a third parallel decode path (required by the AIS class A market.), using an external FSK modem. Integrated Rx/Tx data buffers and a slot/sample timer ...

Amiccom Electronics Corporation (Amiccom) announced a new generation of ultra-low-receiving current sub-GHz RF transceiver, named A7169. Inherited the low-current RF architecture developed by ...

The carrier frequencies for AM operate from 530 kHz to 1610 kHz. Many superheterodyne AM radios use a demodulation circuit designed for 455 kHz. When the listener tunes in a station, an oscillator ...
