powerline carrier (3ru chassis) configured as a transmitter / receiver (tx/rx) for either pott & dtt (ch 1) or dtt (ch 2) application, 125 vdc keying voltage, with 48vdc input voltage, 250vdc 30amp @ 200ms/5amp continuous contact outputs, 50 w, 20 to 500 khz power amplifier with receiver connection and no attenuator/receiver filter, and one 48-125 vdc range power supply.
The solutions used simple modulation techniques like amplitude-shift keying (ASK) or frequency-shift keying
Smartphones, microfluidics, low-power devices, 1-way valves, optical sensing, multiplexed assays, frequency-shift keying
, and lyophilization are not new technologies.
Similarly, frequency-shift keying
(FSK) transmits a "one" on one frequency and a "zero" on another frequency.
The MSK modulation format is a special case of binary frequency-shift keying
(FSK) in which the selected modulation index is h = 0.
When using frequency-shift keying
, there are two limitations.
7V, the versatile ISD61S00 can perform a range of powerful telephony-based communications functions, such as the detection and generation of both dual-tone multi-frequency (DTMF) signaling and frequency-shift keying
(FSK) for Bell 103, Bell 202 or V.
The Existing Communications Utilizes Serial-based Analog Frequency-shift Keying
Aktakom AWG-4151 universal generator can work not only with harmonic signals, but also has modulation opportunities and other special modes including: amplitude modulation (AM), frequency modulation (FM), phase modulation (FM), frequency-shift keying
(FSK), and also operation in pulse width modulation (PWM), sweep mode, frequency and pulse bursts.
With the addition of only a few other peripheral components, the two ICs can be integrated to form a small, cost-effective transceiver capable of transmitting and receiving FM or frequency-shift keying
(FSK) signals in the 860 to 965 MHz frequency range with input data rates up to 500 kbps.
The basic possibilities are amplitude-shift keying (ASKe, phase-shift keying (PSK) and frequency-shift keying
Support for optional frequency-shift keying
(FSK) modulation with a communication bit rate of 150Kbps, operating within specified frequency bands and parameters
