    Sir

    We are tring to transmit digital signal through RF transmitter using only AVR ATmega8A and also receive signal wia RF receiver and give it to the Arduino to process.

    Que is:

    1. Do we require to add encoder between RF tx and AVR ATmega8A ?

    2. Also do decoder at between RF rx and Arduino?

    3. Or not then which AVR we can use or wireless module use for digital communication?

    Please try to response as soon as possible.

    THANKING YOU

    encoders-decoders are required for wireless protocol. they make a packet of user data in wireless protocol format and transmit through RF Tx module that is actually only a carrier signal

    u can develop ur own wireless protocol through programming for ATmega8. in that case u dont need encoder and decoder chips on either side. 

    if u r not able to make protocol then u need endoder-decoder chips like HT12E and HT12D
