Top 31 Analogue Electronics Interview Questions You Must Prepare 06.Jul.2022

The energy is stored as an electric field.

In digital electronics, the fan-out of a logic gate output is the number of gate inputs it can drive.

In most designs, logic gates are connected to form more complex circuits. While no logic gate input can be fed by more than one output, it is common for one output to be connected to several inputs. The technology used to implement logic gates usually allows a certain number of gate inputs to be wired directly together without additional interfacing circuitry. The maximum fan-out of an output measures its load-driving capability: it is the greatest number of inputs of gates of the same type to which the output can be safely connected.

changing the voltage of an alternating-current signal.

Metastability in electronics is the ability of a digital electronics system to persist for an unbounded time in an unstable equilibrium or metastable state. In metastable states, the circuit may be unable to settle into a stable '0' or '1' logic level within the time required for proper circuit operation.

The characteristic impedance or surge impedance (usually written Z0) of a uniform trmission line is the ratio of the amplitudes of voltage and current of a single wave propagating along the line; that is, a wave travelling in one direction in the absence of reflections in the other direction.

Metal-oxide-semiconductor-field-effect-tristor.

The application of electric voltage to a P-N junction is known as Bias.

Load line is used in the graphical analysis of non-linear circuits.

The collector-emitter current with no input.

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

A short circuit has very little resistance.

Signal integrity or SI is a set of measures of the quality of an electrical signal. In digital electronics, a stream of binary values is represented by a voltage (or current) waveform.

In digital electronics three-state, tri-state, or 3-state logic allows an output port to assume a high impedance state in addition to the 0 and 1 logic levels, effectively removing the output from the circuit.

In electronics, a sample and hold (S/H, also "follow-and-hold") circuit is an analog device that samples (captures, grabs) the voltage of a continuously varying analog signal and holds (locks, freezes) its value at a constant level for a specified minimum period of time.

The linear variable differential trformer (LVDT) (also called linear variable displacement trformer, linear variable displacement trducer, or simply differential trformer) is a type of electrical trformer used for measuring linear displacement (position).

frequency modulation technique is the frequency of a carrier signal varied according to the amplitude of an information-bearing signal.

The voltage at which a Zener diode starts conducting when reverse biased is called Breakdown Voltage.

Op Amp Settling Time. SETTLING TIME. The settling time of an amplifier is defined as the time it takes the output to respond to a step change of input and come into, and remain within a defined error band, as measured relative to the 50% point of the input pulse.

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

It is commonly used in at least two contexts:
In a digital circuit, the noise margin is the amount by which the signal exceeds the threshold for a proper '0' or '1'.

In electronics a relaxation oscillator is a nonlinear electronic oscillator circuit that produces a nonsinusoidal repetitive output signal, such as a triangle wave or square wave. The period of the oscillator depends on the time constant of the capacitor or inductor circuit.
