Answer :
The application of electric voltage to a P-N junction is known as Bias.
Question 2. What Is Frequency Modulation?
Answer :
frequency modulation technique is the frequency of a carrier signal varied according to the amplitude of an information-bearing signal.
Answer :
The same amount of current flows through each resistor.
Answer :
The same amount of current flows through each resistor.
Question 5. Which Applications Is A Typical Use For A Transformer?
Answer :
changing the voltage of an alternating-current signal.
Question 6. In What Form Is The Energy Stored In A Charged Capacitor?
Answer :
The energy is stored as an electric field.
Question 7. Under What Physical Conditions Is Magnetic Energy Stored In An Inductor?
Answer :
when current is flowing through the inductor.
Question 8. What Does Mosfet Stand For?
Answer :
Metal-oxide-semiconductor-field-effect-transistor.
Question 9. Which Is True About The Resistance In A "short Circuit?"
Answer :
A short circuit has very little resistance.
Question 10. Which Components Form A Darlington Pair?
Answer :
Two bipolar transistors.
Answer :
The impedance is equal to the resistance.
Answer :
The total capacitance is greater than either of the individual capacitances.
Answer :
The charge is proportional to the applied voltage.
Question 14. What Is Breakdown Voltage?
Answer :
The voltage at which a Zener diode starts conducting when reverse biased is called Breakdown Voltage.
Answer :
The impedance increases with frequency.
Answer :
The total capacitance is less than either of the individual capacitances.
Answer :
Each capacitor has the same voltage drop.
Answer :
The impedance decreases with frequency.
Question 19. What Does A Q-point Of A Transistor Indicate?
Answer :
The collector-emitter current with no input.
Question 20. What Is The Use Of The Load Line?
Answer :
Load line is used in the graphical analysis of non-linear circuits.
Question 21. What Is Tri-state Logic?
Answer :
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.
Question 22. What Is A Relaxation Oscillator?
Answer :
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.
Question 23. What Is Noise Margin?
Answer :
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'.
Question 24. What Is Characteristic Impedance?
Answer :
The characteristic impedance or surge impedance (usually written Z0) of a uniform transmission 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.
Answer :
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.
Question 26. What Is Sample And Hold Circuit?
Answer :
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.
Question 27. Define Settling Time Of Op Amp?
Answer :
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.
Question 28. What Is Gain Bandwidth Product?
Answer :
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.
Question 29. What Is Meta Stability?
Answer :
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.
Question 30. What Is Signal Integrity?
Answer :
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.
Answer :
The linear variable differential transformer (LVDT) (also called linear variable displacement transformer, linear variable displacement transducer, or simply differential transformer) is a type of electrical transformer used for measuring linear displacement (position).
