  2. Phase modulation - Wikipedia

    en.wikipedia.org/wiki/Phase_modulation

    Phase modulation (PM) is a modulation pattern for conditioning communication signals for transmission. It encodes a message signal as variations in the instantaneous phase of a carrier wave . Phase modulation is one of the two principal forms of angle modulation , together with frequency modulation .

  3. Signal generator - Wikipedia

    en.wikipedia.org/wiki/Signal_generator

    RF signal generators produce continuous wave radio frequency signals of defined, adjustable, amplitude and frequency. Many models offer various types of analog modulation, either as standard equipment or as an optional capability to the base unit. This could include AM, FM, ΦM (phase modulation) and pulse modulation.

  4. Function generator - Wikipedia

    en.wikipedia.org/wiki/Function_generator

    Arbitrary waveform generators may have distortion less than -55 dB below 50 kHz and less than -40 dB above 50 kHz. Some function generators can be phase locked to an external signal source, which may be a frequency reference or another function generator. Amplitude modulation (AM), frequency modulation (FM), or phase modulation (PM) may be ...

    The phase modulation (φ(t), not shown) is a non-linearly increasing function from 0 to π /2 over the interval 0 < t < 16. The two amplitude-modulated components are known as the in-phase component (I, thin blue, decreasing) and the quadrature component (Q, thin red, increasing).

  7. Phase-locked loop - Wikipedia

    en.wikipedia.org/wiki/Phase-locked_loop

    A phase-locked loop or phase lock loop (PLL) is a control system that generates an output signal whose phase is fixed relative to the phase of an input signal. Keeping the input and output phase in lockstep also implies keeping the input and output frequencies the same, thus a phase-locked loop can also track an input frequency.

  8. Phase-shift keying - Wikipedia

    en.wikipedia.org/wiki/Phase-shift_keying

    Phase-shift keying (PSK) is a digital modulation process which conveys data by changing (modulating) the phase of a constant frequency carrier wave. The modulation is accomplished by varying the sine and cosine inputs at a precise time. It is widely used for wireless LANs, RFID and Bluetooth communication.

  9. Numerically controlled oscillator - Wikipedia

    en.wikipedia.org/wiki/Numerically_controlled...

    The frequency accuracy relative to the clock frequency is limited only by the precision of the arithmetic used to compute the phase. [4] NCOs are phase- and frequency-agile, and can be trivially modified to produce a phase-modulated or frequency-modulated output by summation at the appropriate node, or provide quadrature outputs as shown in the ...
