Pulse Circuits MCQs : This section focuses on the "Basics" of Pulse Circuits. These Multiple Choice Questions (MCQs) should be practiced to improve the Pulse Circuits skills required for various interviews (campus interview, walk-in interview, company interview), placement, entrance exam and other competitive examinations.
These signals are mainly of _______ types.
Explanation: These signals are mainly of two types named as Unidirectional and Bidirectional signals.
Example of bidirectional signal is?
A. Pulse signal
B. Sinusoidal signal
C. Both A and B
D. None of the above
Explanation: Example : Sinusoidal signal.
The signal when alters in both positive and negative directions crossing the zero point, such a signal is termed as a?
A. Bidirectional Signal
B. Unidirectional Signal
C. Directional Signal
D. Nodirectional Signal
Explanation: Bidirectional Signal : The signal when alters in both positive and negative directions crossing the zero point, such a signal is termed as a Bidirectional signal.
Measurement from any point on one cycle to the same point on next cycle is?
A. Pulse width
B. Duty cycle
C. Rise time
D. Period of a waveform
Explanation: Period of a waveform : Measurement from any point on one cycle to the same point on next cycle
Time signal takes to fall from 90% to 10% of its maximum amplitude is?
A. Rise time
B. Overshoot time
C. Fall time
D. Undershoot time
Explanation: Fall time : Time signal takes to fall from 90% to 10% of its maximum amplitude.
A Switch is a device that makes or breaks a circuit or a contact.
C. Can be yes or no
D. Can not say
Explanation: Yes, A Switch is a device that makes or breaks a circuit or a contact.
How many types of Switches?
Explanation: There are three types of Switches. They are : Mechanical switches, Electromechanical switches or Relays, Electronic switches
Mechanical Switches have high inertia which limits the speed of operation.
C. Can be true or false
D. Can not say
Explanation: True, Mechanical Switches have high inertia which limits the speed of operation.
Electromechanical switches are also called as ?
Explanation: Electromechanical switches are also called as Relays. These switches are partially mechanical and partially electronic or electrical. These are greater in size than electronic switches and lesser in size than mechanical switches.
Which of the following is false about relays?
A. A relay consumes less energy, even to handle a large power at the load.
B. Slow in operation
C. No Sparking while turning ON or OFF
D. The operator can be at larger distance
Explanation: Disadvantages : Slow in operation, Parts are prone to wear and tear
