What is the estimated bandwidth using Carson's rule when your separation is 19.8 kHz, the baud rate 19.2 kBaud/s modulation is FSK, NRZ line coding and the crystal tolerance is negligible? Thanks

If that doesn't work consider that (a) the channel separation is strongly indicative of allowable bandwidth, and (b) without knowing the frequency shift of an FSK signal you can only find a minimum bandwidth, but you can't find the actual bandwidth. -- Tim Wescott Wescott Design Services http://www.wescottdesign.com
