Hello students, the first part of the question is related to the frequency response of amplifier.
00:13
It is a plot versus the output voltage and frequency which is of approximate the shape here the frequency and in the y -axis it is vout.
00:47
So option a, that is the plot is versus the output voltage and frequency is the right answer.
00:55
Moving on to the next part of the question, it is related to the voltage gain of the amplifier.
01:04
The voltage gain g is equal to vout by vin at cut -off frequency.
01:28
The gain of the amplifier, that is g becomes or drops to 70 .7 % of maximum value.
01:45
Therefore gain can be represented as the voltage gain is equal to 0 .707 into the maximum value that is v.
02:12
That is the report answer.
02:14
The voltage gain that is g, that will be gv is equal to 0 .707 into vmid, that is the mid value of the graph.
02:29
Moving on to the third part of the question, it is regarding the unity gain frequency.
02:37
The equation of unity gain frequency, ft is equal to the product of the mid -range voltage into the compensating capacitance, which can be represented as ft is equal to the voltage mid into capacitance...
