Abstract: Over the past decade, tremendous development of Wireless Communications has changed human life and engineering. Considerable advancement has been made in design and architecture of related ...

Compared to the simple diode needed to demodulate AM radio signals, the detector circuits used for FM are slightly more complicated. Wrapping your head around phase detectors, ratio detectors, ...

Phase Shift Keying (PSK) modulation and demodulation circuit simulations (via LTspice and Proteus) also contains the pcb gerbers. This repository contains simulation files and circuit diagrams for ...

ABSTRACT: UM2000 signal is a type of multi-audio frequency-modulated signal which is widely used for railway blocking. Principles of three typical demodulating ...

ABSTRACT: In this paper, a modified FPGA scheme for the convolutional encoder and Viterbi decoder based on the IEEE 802.11a standards of WLAN is presented in OFDM baseband processing systems. The ...

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 ...

Holtek announced the release of its new wireless charger transmitter Flash MCU, the HT66FW2350. The device includes a host of wireless charger transmitter required functions such as AM demodulation ...
