- Because its valence electrons are more tightly bonded to the parent nuclei
Why is biasing important to BJT’s?
- to have a fixed current amplification level
What does thermometer resistor measure?
- Temperature
If the loop gain of the oscillating doesn’t obey Barkhevun(ano daw ‘to?) principle (loop gain = 1), what will happen?
- Stop oscillating
If the MOSFET operates higher than the pinch off voltage, what happens to the drain current?
- the drain current is constant
What do you need in order to get the product of two binary?
- Adder,subtractor and shift register
“Databus” refers to
- data lines in the system bus
Transputer is a

The main advantage of swinburnes?
- economical and convenient
A device with two plate and between them is an insulator
- Capacitor
A device that converts sinewave to series of pulses through the application of comparator circuits
- Timing marker generator
A filter that rejects a band of signals/frequencies and pass the rest
- Bandstop filter
The ratio of fractional difference of amplification with feedback to the fractional difference of amplification without feedback
- sensitivity of transfer gain
Why monolithic ICs are more used than Film ICs?
- because of its linear property
Why is bleeder resistor used in biasing DC circuits?
- to improve regulation and filtration
What must be added to improve its linearity of the bootstrap and time-base miller?
- a compensating network
What must be the reason why amplifier with feedback changes with increasing frequency?
- because of capacitive elements
In hall effect, the electric field is

- Increased
Maxwell L/C bridge is so called because of
- balance of two opposite impedance in opposite arms
Battery buffer
- decreases variation of voltage and current supplied by dc generators
SCS acts ON state by

Access of identity register in a digital computer uses
- address modification
In N channel MOSFET, the value of gate voltage is
