What are blocking oscillator used for?
A blocking oscillator is a waveform generator that is used to produce narrow pulses or trigger pulses. While having the feedback from the output signal, it blocks the feedback, after a cycle, for certain predetermined time.
What are the two types of astable blocking oscillators?
Here, two types of astable blocking oscillators are considered: a diode-controlled astable blocking oscillator and an RC-controlled astable blocking oscillator.
What is a pulse oscillator?
Pulse coupled oscillators are limit cycle oscillators that are coupled in a pulsatile rather than smooth manner.
How does a relaxation oscillator work?
A relaxation oscillator is a repeating circuit (like the flasher circuit illustrated above) which achieves its repetitive behavior from the charging of a capacitor to some event threshold. The event discharges the capacitor, and its recharge time determines the repetition time of the events.
What are the application of oscillator?
Used in computers, metal detectors, stun guns, inverters, ultrasonic and radio frequency applications. Used to generate clock pulses for microprocessors and micro-controllers. Used in alarms and buzzes. Used in metal detectors, stun guns, inverters, and ultrasonic.
What are the advantages of core saturation method of frequency control in a blocking oscillator?
What are tha advantages of core saturation method of frequency control in a blocking oscillator? The pulse duration depends on the supply voltage and characteristics of the core and not on the transistor parameters (hfe). 7. State any two methods of achieving sweep linearity of a time-base waveform.
What is a PWM oscillator?
Pulse-width modulation (PWM), or pulse-duration modulation (PDM), is a method of reducing the average power delivered by an electrical signal, by effectively chopping it up into discrete parts.
What is the difference between pulse and wave?
A wave is a disturbance that causes transfer of energy through space while a pulse is as a result of a single vibration sent through a medium.
What is sinusoidal oscillator?
A sinusoidal oscillator is defined as an oscillator which produces a periodic signal that is in the form of sinusoidal. It is used for the conversion of input energy from a DC source into an AC output energy of the periodic signal.
What is pulse transformer?
A pulse transformer is an enhanced transformer that produces electrical pulses of great velocity and constant amplitude. They are often used in the transmitting of digital information and in transistors (particularly with gate drive circuits).
What is an oscillation transformer?
Description. English: A radio frequency “oscillation transformer” used in a spark-gap radio transmitter from 1913. It consists of two spirals of brass strip mounted on a support rod facing each other so they are magnetically coupled. One coil is connected to a capacitor, making a tuned circuit (tank circuit).
What is stable state in multivibrator?
It functions as a relaxation oscillator. Monostable multivibrator, in which one of the states is stable, but the other state is unstable (transient). A trigger pulse causes the circuit to enter the unstable state. After entering the unstable state, the circuit will return to the stable state after a set time.
