Maybe this is just an error in the schematic, but I noticed the output signal is inverse of the input signal. I.e High-Input is Low-Output.
This makes sense because as the transistor turns on, more current is passed through to ground, if it is low, less current is passed through to ground and...
Thanks. I'm new to electronics, so I'm finding it difficult to understand the terminology and diagrams :X
Hmm. Okay, well. Here's my guess as to what's happening.
R1 and R2 are keeping the transistor in a bias state by creating a large enough voltage drop across R2. When a low AC signal passes...

I understand the first resistor filters out the dc offsets. I know that than some sort of voltage-divider is then used. I'm not sure what the hell it's there for though.
Also, the book says the transistor has to remain in a bias state. Which means, partially on?
I...
