Design a series RLC BPF with
fo_(o)=8kHz
and
Q=2
, using a
5nF
capacitor. a) Find R, L, and the bandwidth. b) Now, rather than an ideal voltage source, assume the source has an impedance of
1k\Omega
(i.e., add a
1k\Omega
resistor in series with the source). Also, there is a load resistor of
5k\Omega
in parallel across
R
. What is the
Q
of the filter with the source and load resistances included? Hint: find the equivalent resistance, then use the same equation for
Q
substituting
R_(eq )
for
R
. c) Simulate the circuit in b) in LTSpice. Find
fo_(0)
and
\beta
from the simulation, and use these to verify Q.
