What are pulse circuits?
A pulse is a burst of current, voltage, or electromagnetic-field energy. In digital circuits, pulses can make the voltage either more positive or more negative. Usually, the more positive voltage is called the high state and the more negative voltage is called the low state.
Which circuit produces pulses?
Pulse Circuits – Multivibrator Overview. A multivibrator circuit is nothing but a switching circuit. It generates non-sinusoidal waves such as Square waves, Rectangular waves and Saw tooth waves etc.
What is the function of a detector circuit?
In radio, a detector is a device or circuit that extracts information from a modulated radio frequency current or voltage.
What is a trigger pulse?
[′trig·ər ‚pəls] (electronics) A pulse that starts a cycle of operation. Also known as tripping pulse.
What is circuit frequency?
Frequency is the rate at which current changes direction per second. It is measured in hertz (Hz), an international unit of measure where 1 hertz is equal to 1 cycle per second. Hertz (Hz) = One hertz is equal to one cycle per second. Cycle = One complete wave of alternating current or voltage.
Is a pulse generator circuit?
A pulse generator is either an electronic circuit or a piece of electronic test equipment used to generate rectangular pulses. Pulse generators are used primarily for working with digital circuits, related function generators are used primarily for analog circuits.
What is a pulse train generator?
The Pulse Train Generator for NI-RFSG is a software add-on for LabVIEW that provides pulse sequence generation featuring compatibility with PXI RF Analog Signal Generators, PXI Vector Signal Generators, and the RF outputs of the PXI Vector Signal Transceiver.
What is detector circuit?
In radio, a detector is a device or circuit that extracts information from a modulated radio frequency current or voltage. In a superheterodyne receiver the term is also sometimes used to refer to the mixer, the tube or transistor which converts the incoming radio frequency signal to the intermediate frequency.
What does a pulse signal mean in a circuit?
A train of pulses indicate a sudden high level and a sudden low level transition from a baseline level which can be understood as ON/OFF respectively. Hence a pulse signal indicates ON & OFF of the signal.
How are digital output lines and pulse trains related?
The computers’ digital output lines often control relays that switch signals or power delivered to other equipment. Similarly, digital input lines can represent the two states of a sensor or a switch, while a string of pulses can indicate the instantaneous position or velocity of another device.
How does a pulse train control drive work?
A PLC or other indexer outputting pulse train signals to a pulse train controlled drive. An absolute move transports the carriage to the commanded position regardless of its current position.
What is the bandwidth of a periodic pulse train?
In natural sampling, the continuous-time signal g ( t ), whose bandwidth is W, is multiplied by a periodic pulse train, where each pulse has width τ and amplitude 1 τ, occurring with period Ts. This multiplication can be viewed as the opening and closing of a high-speed switch.
