Radio

• 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?
• AM is allowed +- 5kHz
• 96kHz of bandwidth (due to what the audio card can sample)

• SI570 can create a number of frequencies
