ELEC 332
Design Challenge
This week's design challenge is pretty simple:
build a microphone amplifier to allow our simple transmitter
to transmit speech as well as sine waves.
Your circuit should fit on a 1.5 x 1.5 inch breadboard module
(BRD1x1),
use a Kobicon 161-3507 jack for the microphone input,
and an SMB connector for the amplified output.
When used with the dynamic microphone from the ELEC 241 lab,
and speaking at a normal level, the output should sufficient
to fully modulate signal from the AM transmitter module.
Your design should use parts that are available from stock
(we have the phone jacks and SMB connectors).
If you're feeling nostalgic, you can use thru-hole components
from the 342 parts bins, but surface mount should be easier to fit into
the limited space.
