The spectral shear is typically generated by sum-frequency mixing the test pulse with two different quasi-monochromatic frequencies (usually derived by chirping a copy of the pulse itself), although it can also be achieved by spectral filtering or even with linear electro-optic modulators for picosecond pulses.
A digital pattern generator is a piece of electronic test equipment or software used to generate digital electronic stimuli. Digital electronics stimuli are a specific kind of electrical waveform varying between two conventional voltages that correspond to two logic states ("low state" and "high state", "0" and "1").
where Δi p is the differential current peak value, A is the surface area of the electrode, C 0 * is the concentration of the species, D 0 is the diffusivity of the species, t p is the pulse width, and ΔΨ p is a dimensionless parameter which gauges the peak height in SWV relative to the limiting response in normal pulse voltammetry.

The pulse-repetition frequency (PRF) is the number of pulses of a repeating signal in a specific time unit. The term is used within a number of technical disciplines, notably radar. In radar, a radio signal of a particular carrier frequency is turned on and off; the term "frequency" refers to the carrier, while the PRF refers to the number of ...
A digital delay generator (also known as digital-to-time converter) is a piece of electronic test equipment that provides precise delays for triggering, syncing, delaying, and gating events. These generators are used in many experiments, controls, and processes where electronic timing of a single event or multiple events to a standard timing ...
A record number of U.S. CEOs exited their jobs this year, according to Challenger, Gray & Christmas, which said companies are responding to an uncertain landscape by installing temporary leaders ...
After the war, Gallagher resumed manufacturing gas producers, setting up a facility at his property on Seddon Road in Hamilton and employing six workers. His business also carried out tractor conversions and made farming equipment, including his battery-powered electric fence. With his brothers, Henry and Vivian, he invented a spinning top-dresser.
Examples of pulse shapes: (a) rectangular pulse, (b) cosine squared (raised cosine) pulse, (c) Dirac pulse, (d) sinc pulse, (e) Gaussian pulse. A pulse in signal processing is a rapid, transient change in the amplitude of a signal from a baseline value to a higher or lower value, followed by a rapid return to the baseline value. [1]
