This breakthrough provided quicker response to larger signal transitions from the power amplifier to speakers (reproducers).
Each signal transition provides an opportunity for the receiver to see the transmitter's clock.
These modulations carefully shape the I and Q waveforms such that they change very smoothly, and the signal stays constant-amplitude even during signal transitions.
The effects of receiving delayed and distorted versions of the signal can be seen in the loss of definition of the signal transitions.
Bipolar encoding is preferable to non-return-to-zero where signal transitions are required to maintain synchronization between the transmitter and receiver.
Miller, or delay encoding, works by varying the time between signal transitions depending the sequence of bits compared to a clock signal.
This allows the "master" latch to store the input value when the clock signal transitions from low to high.
A change from one significant condition to another is called a signal transition.
In accordance with Manchester encoding, the bit value is defined by a signal transition in the middle of the bit period.
Slave devices measure the time necessary to receive the 0x55 byte by counting signal transitions.
