- BPF
- LPF+HPF=BPF
- What frequency range?
- How to implement? RL? RC? Do I need something more?
- Amplifier
- Do we need an amplifier? Is the incoming signal large enough?
- LPF:
- What frequency range?
- How to implement?
- Oscillator:
- Outputs a logic high and logic low. What is the best way to convert this to a co/sine wave (multiplex?)
- What value are we looking for?
- Frequency Range:
- FM is most likely too high to create
- AM radio (car stereo) is about right. Find a station you want to tune to. KFBK 1530?
- 96kHz of bandwidth (due to what the audio card can sample)
- SI570 can create a number of frequencies
