What does a blocking oscillator do?
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 oscillator?
Here, two types of astable blocking oscillators are considered: a diode-controlled astable blocking oscillator and an RC-controlled astable blocking oscillator.
Which blocking oscillator is used to generate a single pulse?
A pulse transformer is used as a coupling element in a blocking oscillator to provide positive feedback. If the blocking oscillator generates a single pulse, the circuit is called a monostable circuit.
What are the advantages of core saturation method of frequency control in a blocking oscillator?
6. 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).
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 are the two important elements of blocking oscillator?
A blocking oscillator (sometimes called a pulse oscillator) is a simple configuration of discrete electronic components which can produce a free-running signal, requiring only a resistor, a transformer, and one amplifying element such as a transistor or vacuum tube.
Which of the following is not an example of a sinusoidal oscillator?
blocking oscillator
Which of the following is not an example of sinusoidal oscillator? Explanation: A blocking oscillator is a non-sinusoidal oscillator. It produces a free running signal-square shaped and requires only a resistor, transformer and one amplifying element to work.
What are the individual blocks of an oscillatory circuit?
What are pulse transformers?
Pulse Transformers are designed to transfer pulses (signals/voltage with a rapid rise time, a duration of constant signal/voltage, and then a rapid fall time) from one side of a circuit to another.
