List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE. The following table is split into two groups based on whether it has a graphical visual interface or not.
Then their state can be read by an encoder to determine the delay. In general a digital delay-line based TDC, [19] also known as tapped delay line, contains a chain of cells (e.g. using D-latches in the figure) with well defined delay times . The start signal propagates through this chain and is successively delayed by each cell.
A digital delay line (or simply delay line, also called delay filter) is a discrete element in a digital filter, which allows a signal to be delayed by a number of samples. Delay lines are commonly used to delay audio signals feeding loudspeakers to compensate for the speed of sound in air, and to align video signals with accompanying audio ...
A direct form discrete-time FIR filter of order N.The top part is an N-stage delay line with N + 1 taps. Each unit delay is a z −1 operator in Z-transform notation. A lattice-form discrete-time FIR filter of order N.
A time delay and integration or time delay integration (TDI) is a forward motion compensation (FMC) technique for capturing images of moving objects at low light levels. It's a type of line scanning where multiple linear arrays are placed side by side. After the first array is exposed, the charge is transferred to the neighboring line.
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 ...
One example of an analog delay line is a bucket-brigade device. [1] Other types of delay line include acoustic (usually ultrasonic), magnetostrictive, and surface acoustic wave devices. A series of resistor–capacitor circuits (RC circuits) can be cascaded to form a delay. A long transmission line can also provide a delay element. The delay ...
In this scheme, a "tapped delay line" reinforces the desired frequencies as the sound waves flow across the surface of the quartz crystal. The tapped delay line has become a general scheme of making high- Q filters in many different ways.
