how to do with 89C2051 ? Let says that FSK modulator had solved by using ladder resistors at one ports.. You can demod the FSK by using Op-amp(or op-amp inside MCU) as comparator.."from sinewave to became square(digital)".. using code..you can demod the FSK. http://www.baycom.org http://gb7tvg.dnsalias.net/~tvipug/ look how they make ladder resistors. There's lot of TNC designers using ladder resistors for FSK/AFSK modulator. and with op-amp as demodulator. Thank's Jeckson Ben |
