Hi. i need to feed the demodulated data to an 8051 to its RxD pin. bt the demodulated output is not like a signal an 8051 would recieve bcz
1. the demod signal has two voltage levels. a positive(400mV) and a negative(-600mV). while to my knowledge i'll have to shape to a signal which only has a positive level of 5V and the negative level should be clipped to 0V.
2. the demod data has also reduced the duty cycle. the negative level is smaller and the upper's spans more. so i need to make the duty cycle 50%.
how do i do this? plz help. thanks.
