For example, the pulse repetition rate and duration may be digitally controlled but the pulse amplitude and rise and fall times may be determined by analog circuitry in the output stage of the pulse generator. With correct adjustment, pulse generators can also produce a 50% duty cycle square wave. Pulse generators are generally single-channel ...
In some designs (as shown in the diagrams) the secondary voltage V s adds to the source voltage V b; in this case because the voltage across the primary (during the time the switch is closed) is approximately V b, V s = (N+1)×V b. Alternately the switch may get some of its control voltage or current directly from V b and the rest from the ...
Internal block diagram [1] The 555 timer IC is an integrated circuit used in a variety of timer , delay, pulse generation, and oscillator applications. It is one of the most popular timing ICs due to its flexibility and price.
The sinc pulse is of some significance in signal-processing theory but cannot be produced by a real generator for reasons of causality. In 2013, Nyquist pulses were produced in an effort to reduce the size of pulses in optical fibers, which enables them to be packed 10 times more closely together, yielding a corresponding 10-fold increase in ...
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 sawtooth shapes .
The block diagram below shows the basic elements and arrangement of a PLL based frequency synthesizer. Block diagram of a common type of PLL synthesizer. The key to the ability of a frequency synthesizer to generate multiple frequencies is the divider placed between the output and the feedback input.

Each of the handwheels on this CNC control actuates a manual pulse generator. One moves the cross-slide (X-axis) and the other moves the Z-axis A manual pulse generator ( MPG ) is a device for generating electrical pulses (short bursts of low current ) in electronic systems under the control of a human operator (manually), as opposed to the ...
