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 ...

Partial dynamic reconfiguration is a radical new way to configure and reprogram an FPGA. Unlike the standard FPGA reconfiguration process, PDR allows you to change a small part of the device based on ...

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 ...

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 ...

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 ...

The first decoding attempt used the FreqMeasure library written by [Paul Stoffregen]. After no success they moved to a hardware solution in the form of the XR-2211 FSK Demodulator chip.

Because the network in the modulator circuit has two floating differential outputs, the demodulator network requires two floating sources. The simplest way to accomplish this requirement is by using ...

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 ...
