Fsk theory
WebBinary FSK (a) and PSK (b) modulation. The modulated output of a direct digital synthesizer (DDS) can switch frequency and/or phase in a phase-continuous or phase-coherent manner, as shown in Figure 1, and as described in “Multichannel DDS Enables Phase-Coherent FSK Modulation,” making DDS technology well suited for both FSK and PSK modulation. WebTheory. Frequency Shift Keying Signal. Theory. The FSK signal switches between two frequencies. The frequency of the signal that corresponds with logic-Os in the digital data called the space frequency is usually lower …

In this, the frequency shift is generally proficient by motivating a VCO with the binary data signal. So that the two subsequent frequencies …
Frequency-shift keying (FSK) is a frequency modulation scheme in which digital information is encoded on a carrier signal by periodically shifting the frequency of the carrier between several discrete frequencies. The technology is used for communication systems such as telemetry, weather balloon … See more Reference implementations of FSK modems exist and are documented in detail. The demodulation of a binary FSK signal can be done using the Goertzel algorithm very efficiently, even on low-power … See more Multiple frequency-shift keying Continuous-phase frequency-shift keying In principle FSK can be implemented by using completely … See more Frequency-shift keying (FSK) is commonly used over telephone lines for caller ID (displaying callers' numbers) and remote metering applications.
