What does the Ø symbol mean?
ø means the Greek letter and numerical approximation It is used to indicate the phase of a signal.
What does an amplifier do to a small input signal?
amplifier will strengthen da small input signal n amplifies it
A Triac is used to switch?
Large a.c. currents with a small trigger signal.
Why small signal equivalent model is needed?
to calculate and measure the impedance ,admittance is simple
Why power diode has more power ratings?
It will be dissipating more power than a small signal diode.
How can you tell if a linear appoximation is too large or too small?
The precision of a linear approximation is dependent on the concavity of the function. If the function is concave down then the linear approximation will lay above the curve, so it will be an over-approximation ("too large"). If the function is concave up then the linear approximation will lay below the curve, so it will be an under-approximation ("too small").

What is small signal amplifier?
As the name suggests, it amplifies a small signal. It ususally has a very high input impedance, to avoid affecting the source signal.
Whats the main difference between small signal amplifier and large signal amplifier?
1.Small signal amplifier can be designed easily using s parameter while large signal amplifier not.
How small is small ie small approximation of up to which angle of physical pendulum in calculating time period?
Small- little short not very important Small- little short not very important
Different between power transistor and transistor that used in small signal?
Power transistor can conduct large amount of currents through it, more than small signal transistor. power transistor has a vertical structure and small signal transistor has horizontal structure.In power transistor quasi saturation region is present which is absent in the small signal transistor. In power transistor there is a inculsion of drift layer which is not there in the small signal transistor. Power dissipation is less in power transistor and it is more in small signal transistor. b.v.polytechnic,vasai pushkar vaity.
What is the difference between small and large signal?
small signal basically it's about linear operation around the quiesient point. large signal is actually talking about "total signal". so just take both dc and ac into account.
What is meant by the term small signal amplifier?
Small signal amplifiers are generally referred to as "Voltage" amplifiers as they convert a small input voltage into a much larger output voltage.
Magnifies a small electric signal?
an amplifier.
What magnifies small electric signal?
An amplifier.
Why do you need small signal amplifier?
Small signal amplifier is needed because it is used for amplifying input signals having low frequency or amplitude.
