What is meant by free oscillation?
1 : the oscillation of a body or system with its own natural frequency and under no external influence other than the impulse that initiated the motion. — called also free vibration. —opposed to forced oscillation.
What is the purpose of an oscillator?
Oscillators convert direct current (DC) from a power supply to an alternating current (AC) signal. They are widely used in many electronic devices ranging from simplest clock generators to digital instruments (like calculators) and complex computers and peripherals etc.
What are Barkhausen conditions for oscillation?
Generally, the Barkhausen criteria has two conditions, first the closed-loop gain is equal to 1, second the closed-loop phase is equal to 0, with these conditions, the oscillator circuit would generate a sinusoidal signal.
Which oscillator is more accurate Mcq?
So oscillator frequency is more stable and accurate. Hence Clapp oscillator have more accurate frequency. What will be the clapp oscillator frequency if the C1, C2, C3 of clap oscillator is 1μF, 1μF, 2μF respectively and inductance is 1μH?
What happens if Aß |< 1 *?
Explanation: When Aß=1, the feedback signal will be equal to the input signal. At this condition, the circuit will continue to provide output, even if the external signal is disconnected. This is because the amplifier cannot distinguish between external signal and signal from the feedback circuit.
What is IC 723 MCQ?
This set of Analog Circuits Multiple Choice Questions & Answers (MCQs) focuses on “Voltage Regulators – 1”. Explanation: The IC 723 is a voltage regulator, which can act as both a low voltage regulator as well as a high voltage regulator. Output can be set between 7-37 volts. 7 volts is the reference starting voltage.
When bridge oscillator is most often used whenever?
Wien bridge oscillator is most often used whenever. B. phase shifting the output by 1800 and feedingothis phase-shifted output to the input.
Why do we use Wein bridge oscillator?
The Wien bridge is one of many common bridges. Wien’s bridge is used for precision measurement of capacitance in terms of resistance and frequency. It was also used to measure audio frequencies.
