Data Pulse Widths
(SeeNote 2)
0.5
1. IF bandwidth available down to 27KHz
2. The data slicer is optimised for a 50:50 duty cycle, hence for reliable communications data should be
encoded using a suitable scheme such as Manchester Encoding, though pulse width modulation up to
30:70/70:30 can also be utilised.
