For coherent frequency shift keying
modulation is characteristic that, each 1 or 0 bites have equal phase ratio to referential phase.
FSK Frequency Shift Keying
A modulation technique that assigns one tone to a 1 and another tone to a 0.
The PHY uses 2-or 4-level Gaussian frequency shift keying
11b RF and NB-FSK PLC (SAE J 2931/2) frequency shift keying
(FSK), and power line communication (PLC).
ZigBee nodes will cost more, decrease battery life, and offer less range than proprietary sub-GHz technologies using frequency shift keying
Diverse RFID variants use differing modulation formats: On/off keying (OOK), pulse code modulation (PCM), amplitude shift keying (ASK), frequency shift keying
(FSK) and more.
This type of transmission is referred to as frequency shift keying
The transceiver includes RF signal synthesis, a frequency shift keying
(FSK) transmitter; a direct down-conversion receiver and a feature-rich digital interface.
This process is basically independent of the modulation content of the desired carrier; analog amplitude modulated (AM), frequency modulated (FM), digital frequency shift keying
(FSK) or quadrature phase shift keying (QPSK).
