We need to design electronic circuits that makes digital audio transmission and reception ; so it will consists of two circuits : transmission circuit and reception circuit and will have the following specifications :
1-the audio sampling rate should be as high as possible
2- Each audio sample will be preceded by the transmitter identification and followed by the [Sample End indication] as shown in the attachments
3- The carrier frequency should be between 300MHz and 450MHz to avoid any interference with the FM stations
4- The circuits component should be available and at low costs as much as possible but not affect the circuit efficiency
5- If there is a usage of microcontroller, you should use pic18f2550, as it is suitable for our market and our pic programmers.
6- The transmission range should not be less than 25 meter
7- The designs should be accompanied by a simulation which prove and confirm its performance where it is possible to do
8- The design should be attached with...
