Lab #8
Although circuit diagrams do not show Pin #4 and 7 connection (DC power), they
should be connected to +/- 12 V.
8-1 Follow the instruction. You cannot measure the open loop gain (OLG) precisely but
can give lower bound of the OLG
8-2 Follow the instruction.
8-3 Follow the instruction. Be aware of the input impedance of your OSC.
8-4 Follow the instruction.
8-5 Follow the instruction. Skip the VP01 part.
8-6 Follow the instruction. (a) LPT100 is obsolete. We will replace it with BPW46. You
will see a small ac signal on top of dc signal. Measure the amplitude of the ac part and
compare it with the dc level. Skip (b) and (c).
8-7 Skip.
8-8 Follow the instruction. Skip the parts that involve a breadboard speaker. You do not
need to answer the questions under “Listen to this improved waveform.”
What happens to the shape of the output as the frequency increases from 100Hz to
500Hz?
