A signal generator is one of a class of electronic devices that generates electrical signals with set properties of amplitude, frequency, and wave shape. These generated signals are used as a stimulus for electronic measurements, typically used in designing, testing, troubleshooting, and repairing electronic or electroacoustic devices, though it often has artistic uses as well.
A pseudorandom binary sequence (PRBS), pseudorandom binary code or pseudorandom bitstream is a binary sequence that, while generated with a deterministic algorithm, is difficult to predict [ 1 ] and exhibits statistical behavior similar to a truly random sequence. PRBS generators are used in telecommunication, such as in analog-to-information ...
MUSIC method assumes that a signal vector, , consists of complex exponentials, whose frequencies are unknown, in the presence of Gaussian white noise, , as given by the linear model. n {\displaystyle \mathbf {x} =\mathbf {A} \mathbf {s} +\mathbf {n} .} is the amplitude vector. A crucial assumption is that number of sources,
QtJambi. QtJambi is a Java binding of the cross-platform application framework Qt. It enables Java developers to use Qt within the Java programming language. In addition, the QtJambi generator can be used to create Java bindings for other Qt libraries and future versions of Qt. Unlike GTK, there are no Swing LAF implementations that use Qt for ...
A DDS function generator. Direct digital synthesis (DDS) is a method employed by frequency synthesizers used for creating arbitrary waveforms from a single, fixed-frequency reference clock. DDS is used in applications such as signal generation, local oscillators in communication systems, function generators, mixers, modulators, [1] sound ...
Function generator. In electrical engineering, a function generator is usually a piece of electronic test equipment or software used to generate different types of electrical waveforms over a wide range of frequencies. Some of the most common waveforms produced by the function generator are the sine wave, square wave, triangular wave and ...
Parity bits are generally applied to the smallest units of a communication protocol, typically 8-bit octets (bytes), although they can also be applied separately to an entire message string of bits. The parity bit ensures that the total number of 1-bits in the string is even or odd. [1]
The network analyzer needs a test signal, and a signal generator or signal source will provide one. Older network analyzers did not have their own signal generator, but had the ability to control a stand-alone signal generator using, for example, a GPIB connection. Nearly all modern network analyzers have a built-in signal generator.
