Which of the following are applications of 555 timer Mcq?

The 555 timer IC is an integrated circuit used in a variety of timer, pulse generation, and oscillator applications. Astable mode – In this mode, the 555 IC can be used as an oscillator, pulse generator, logic clocks, etc.

What is 555 timer explain its benefits & gives its applications?

555 timer IC is an integrated circuit used in a variety of applications like Timer, multivibrator, pulse generation, oscillators, etc. It is a highly stable controller capable of producing accurate timing pulses. With Mono-stable operation, the delay is controlled by one external resistor and one capacitor.

Which application uses differentiator?

Which application use differentiator circuit? Explanation: The differentiators are used in FM modulator as a rate of change detector.

Which is the application of a monostable 555 multivibrator Mcq?

4. A monostable multivibrator has R = 120kΩ and the time delay T = 1000ms, calculate the value of C? => C = T/(1.1R) = 1000ms/(1.1×120kΩ) = 7.57µF. 5.

What is the application of timer?

The timer can be used to measure the time elapsed or the external events occurring for a specific time interval. They are used to maintain the operation of the embedded system in sync with the clock. The clock can be an external clock or the system clock.

What are the application fields of timer?

The idea of application timers was introduced in an earlier article. They are kernel objects that provide tasks with simple means to time events or, more commonly, perform an activity on a regular basis. All the detail of timing functionality – accuracy, interrupt handling, etc.

Why capacitor is used in differentiator?

The input signal to the differentiator is applied to the capacitor. The capacitor blocks any DC content so there is no current flow to the amplifier summing point, X resulting in zero output voltage. However, at high frequencies an op-amp differentiator circuit becomes unstable and will start to oscillate.

What is triangular wave generator?

A triangular wave generator is an electronic circuit, which generates a triangular wave. The block diagram of a triangular wave generator is shown in the following figure − The block diagram of a triangular wave generator contains mainly two blocks: a square wave generator and an integrator.
