Phase noise is the frequency-domain representation of random fluctuations in the phase of a waveform, corresponding to time-domain deviations from perfect periodicity (jitter). Learn about the definitions, background, measurement, and spectral purity of phase noise in signal processing and radio-frequency engineering.
A single-photon avalanche diode (SPAD) is a solid-state photodetector that can detect single photons and generate trigger pulses. Learn about its operation, structures, applications, and materials from this Wikipedia article.
Jitter is the deviation from true periodicity of a signal, often in relation to a reference clock signal. Learn about the different types of jitter (random, deterministic, sampling, packet), how to measure and quantify them, and their effects on various applications.
A voltage-controlled oscillator (VCO) is an electronic oscillator whose frequency is controlled by a voltage input. Learn about the types, frequency control, phase-domain equations, design and circuits of VCOs, and their applications in synthesizers, modulation, and phase-locked loops.
Max, also known as Max/MSP/Jitter, is a visual programming language for music and multimedia developed and maintained by San Francisco-based software company Cycling '74. Over its more than thirty-year history, it has been used by composers, performers, software designers, researchers, and artists to create recordings, performances, and ...
Learn how radar systems use radio-frequency electromagnetic signals to determine information about targets. Explore the time domain characteristics of the transmitted and received signals, such as carrier, pulse width, pulse repetition frequency, and clutter.
Injection locking is the frequency effect that occurs when a harmonic oscillator is disturbed by a second oscillator operating at a nearby frequency. Learn about the history, types, and uses of injection locking in electronic and laser oscillators, as well as unwanted injection locking and entrainment.
Learn about PDV, the difference in end-to-end one-way delay between selected packets in a network flow. Find out how to measure, visualize and limit PDV and its effects on multimedia and VoIP applications.
