    hello,
    Can anyone please help me out in this problem related to communication.... how can i transmit a message signal (mostly sinusoidal..eg from signal generator) of freq ranging from 100hz to 1Mhz wirelessly over a short range(<10m) .which modulation technique should i use .analog or digital.its urgent please,.. i m stuck in my final year project here.

    Use encoder with digital signal. I use it in my project.

    P.S: I don't know much about communication 😔 but I used above for lower rating.

    i dint get u... u mean i l ve to use some dsp to code the signals and transmit it...?I actualy wanted to send it to a dsp for further processing! my transmitter part should contain very less components like only adc(if digital modulation techniques r used) and a modulator circuit for transmitting not much....
