Typically ,- 15 V.e-10°. R-1202 and G-2; therefore to give Four-5 V,
R, must be 1 MO
A.C. amplifier
Figure 9.12 shows an ac. signal source connected to an inverting amplifier with
input resistance Re capacitance Ce feedback resistance R, and capacitance C
The circuit can be analysed using ogn [9.27] with R., and R, replaced by complex
impedances Z, and Z, to give:
V R. Cas

Here Zo is the series combination of Ra and C Le
Zou = Rox + (1/Cp)
where is the Laplace operator.
Z, is the parallel combination of R, and C, ie:
Z₁=-
From these equations, the transfer function relating output voltage Foto input voltage
V for the ac. amplifier, is
[9.32]
Figure 9.13 shows the amplitude frequency response characteristics of the amplifier.
It has a mid-band gain of R, R., and a bandwidth between f, and f, and can be used
in a.c. carrier systems (Section 9.3).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F44493e53-879b-4b7e-91d6-3b158a8a6000%2F26996540-e3ae-4d90-aa95-4237a8e76ce8%2Fgilwbu_processed.jpeg&w=3840&q=75)
