I am a bit of a noob to electronics with some soldering experience but incrreasing I feel I need to learn a bit more about electronics
I have a project where it seems sensible to record rs232 data along with video data so I thought why not use the not very compressed pcm audio tracks(24bit 48Khz). The inputs to these are analogue.
I would like to take the tx from an rs232 data stream +-25volts normally maybe +-15voilts and transformer it down to +-1.736V so I can record it as anolugue->digital audio.
I should be able to get my data in the sample rates, assuming I don't go above Nyqvist law so max 24000 bits per second?
1) Can anyone suggest a circuit/components that could reduce the rs232 tx voltage to broadcast line level audio +-1.736V?
2) I asume a simple amp at the other end could transform these logic levels back up to around +-15volts rs232 levels. Can anyone suggest an amplifier?
Many Thanks
