Sleep mode, that is with tx and rx not enabled

2.

1 Hz = 2 bps

3.

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, although pulse

width modulation up to 70:30/30:70 can also be used.
