The time-stretch analog-to-digital converter (TS-ADC), also known as the time-stretch enhanced recorder (TiSER), is an analog-to-digital converter (ADC) system that has the capability of digitizing very high bandwidth signals that cannot be captured by conventional electronic ADCs.

Time-to-digital converter

In electronic instrumentation and signal processing, a time-to-digital converter (TDC) is a device for recognizing events and providing a digital representation of the time they occurred. Analog-to-digital converter and time-to-digital converter are digital signal processing.

Total harmonic distortion

The total harmonic distortion (THD or THDi) is a measurement of the harmonic distortion present in a signal and is defined as the ratio of the sum of the powers of all harmonic components to the power of the fundamental frequency.

TV tuner card

A TV tuner card is a kind of television tuner that allows television signals to be received by a computer.

Two's complement

Two's complement is the most common method of representing signed (positive, negative, and zero) integers on computers, and more generally, fixed point binary values.

Undersampling

In signal processing, undersampling or bandpass sampling is a technique where one samples a bandpass-filtered signal at a sample rate below its Nyquist rate (twice the upper cutoff frequency), but is still able to reconstruct the signal.

Video

Video is an electronic medium for the recording, copying, playback, broadcasting, and display of moving visual media.

Video Graphics Array

Video Graphics Array (VGA) is a video display controller and accompanying de facto graphics standard, first introduced with the IBM PS/2 line of computers in 1987, which became ubiquitous in the IBM PC compatible industry within three years.

Volt

The volt (symbol: V) is the unit of electric potential, electric potential difference (voltage), and electromotive force in the International System of Units (SI).

See Analog-to-digital converter and Volt

Voltage

Voltage, also known as (electrical) potential difference, electric pressure, or electric tension is the difference in electric potential between two points.

Voltage-controlled oscillator

A voltage-controlled oscillator (VCO) is an electronic oscillator whose oscillation frequency is controlled by a voltage input.

Voltmeter

A voltmeter is an instrument used for measuring electric potential difference between two points in an electric circuit.

Weighing scale

A scale or balance is a device used to measure weight or mass.

White noise

In signal processing, white noise is a random signal having equal intensity at different frequencies, giving it a constant power spectral density.

Wideband

In communications, a system is wideband when the message bandwidth significantly exceeds the coherence bandwidth of the channel.
