Dear Community,
I need your help - for a extended school project (Topic: Effective transmission of sound) I'll have to build up a fully-functional wireless audio receiver.
How I realize it (digital/analog) is doesn't matter - but the "big thing" is, that it needs to be as small as possible because the hole project should be realized as a pair of wireless in-ear buds.
Because of the limited battery size (~1/4AAA or button cell) and therefore the limited capacitance, the circuit should work - if possible - with:
- Supply Voltage = 1.2V
- Current ~ 0 - 10mA (if somehow possible)
- And of course: as small realizable as possible!
- Preferred -> Frequency modulation, because of its high stability
At the moment I'm not really sure, if it's better to do the transmission digitally or analog - as far as I know, it's maybe more current-saving doing it all analog (µ-Power FM receiver?)?
But because I'm not sure - I'm asking YOU!
I'll appreciate every advice and suggestion of yours. Of course - circuits (or snipets of) are more than welcome
Thank You in advance.
