Question { TATA, 55232 }

what is transistor biasing?why it is necessary?


Answer

biasing is nothing but external energy applied across base
terminal to activate the transistor. it is neccessary
because to work transistor is properly. stabilisation is for
maintaining a q point stable.emitter resistance is for this
purpose.

Is This Answer Correct ?    13 Yes 6 No

Question { 10776 }

what is difference between feedback oscillator & relaxation oscillator?


Answer

above are right. along with those relaxation oscillators has
higher frequency stability. fb oscillators has low because
those contains rlc components which are dependent on
temperature.

Question { BEL, 5668 }

why does the current through inductor is constant, why
current through inductor & voltage across capacitor is
constant? can u explin clearly?


Answer

current is nothing but flow of electrons in a closed path.
inductor is a passive element which has continuoes coil. so
current is continuoes through inductor. voltage is nothing
but potential difference between two points separated by a
distance. capacitor has a two plates separated by a
dielectric material. so voltage across capacitor is continuoes.

Question { 9835 }

Frequency response of integrator is same as that of
a. high pass filter
b. low pass filter
c. band pass filter
d. band reject filter


Answer

b. becoz in the starting of integrator resistor is there.
thats why it allows some part of the signals called low pass
filter.

Question { 5190 }

In which of the following is an operational amplifier
(op-amp) used?
a. Oscillators
b. Filters
c. Instrumentation circuits
d. All of the above


Answer

oscillators can made by using op-amps. ex;wein bridge
oscillator. in instrumentation also uses. iin filters also
used as a subtractor. the unwanted is given to the inverting
terminal and total signal is given to the non inverting
terminal. output is wanted nothing but filtered.so answer is
all the above.

d. no feedback


Answer

no feedback.
