Printed Circuit Board Design (PCB) Interview Questions
Question 19. What Does A Q-point Of A Transistor Indicate?

The collector-emitter current and not using a input.

Question 20. What Is The Use Of The Load Line?

Load line is used inside the graphical evaluation of non-linear circuits.

Question 21. What Is Tri-kingdom Logic?

In digital electronics three-state, tri-state, or three-state common sense permits an output port to anticipate a excessive impedance state similarly to the zero and 1 good judgment tiers, effectively putting off the output from the circuit.

Question 22. What Is A Relaxation Oscillator?

In electronics a relaxation oscillator is a nonlinear digital oscillator circuit that produces a nonsinusoidal repetitive output signal, together with a triangle wave or rectangular wave. The length of the oscillator depends on the time constant of the capacitor or inductor circuit.

Question 23. What Is Noise Margin?

In electrical engineering, noise margin is the amount by which a signal exceeds the minimal amount for correct operation.

It is normally used in as a minimum two contexts:
In a virtual circuit, the noise margin is the amount with the aid of which the signal exceeds the brink for a right '0' or '1'.

Question 24. What Is Characteristic Impedance?

The feature impedance or surge impedance (commonly written Z0) of a uniform transmission line is the ratio of the amplitudes of voltage and modern-day of a unmarried wave propagating alongside the line; that is, a wave journeying in a single path inside the absence of reflections inside the different route.

Microwave and Optical link Installation Interview Questions
Question 25. What Is Fan Out?

In virtual electronics, the fan-out of a common sense gate output is the wide variety of gate inputs it may pressure.

In maximum designs, common sense gates are linked to form greater complicated circuits. While no good judgment gate enter can be fed by using more than one output, it's miles common for one output to be connected to several inputs. The era used to put in force good judgment gates generally allows a positive range of gate inputs to be stressed out at once collectively with out extra interfacing circuitry. The maximum fan-out of an output measures its load-using functionality: it's far the finest variety of inputs of gates of the equal type to which the output can be properly related.

Question 26. What Is Sample And Hold Circuit?

In electronics, a sample and preserve (S/H, additionally "follow-and-keep") circuit is an analog tool that samples (captures, grabs) the voltage of a constantly various analog sign and holds (locks, freezes) its value at a consistent stage for a distinct minimum time period.

Question 27. Define Settling Time Of Op Amp?

Op Amp Settling Time. SETTLING TIME. The settling time of an amplifier is defined because the time it takes the output to reply to a step trade of enter and come into, and continue to be inside a described blunders band, as measured relative to the 50% factor of the input pulse.

Question 28. What Is Gain Bandwidth Product?

The benefit–bandwidth product (special as GBWP, GBW, GBP or GB) for an amplifier is the product of the amplifier's bandwidth and the advantage at which the bandwidth is measured.
