Abstract
Apparatuses and a method for transmitting a counter signal in an imaging system are provided. Counter states of the counter signal are Gray coded to Gray coded counter states before transmission. Every second Gray coded counter state is inverted to an inverted counter state. The Gray coded counter states inverted in every second counter state are transmitted and are decoded on receipt.
Claims9
A method for transmitting a counter signal in an imaging system, the method comprising:
- coding counter states of the counter signal to Gray coded counter states before transmission;
- inverting every second Gray coded counter state of the Gray coded counter states to an inverted counter state;
- and
- transmitting the inverted counter states.
An apparatus for processing a counter signal to be transmitted in an imaging system, the apparatus comprising:
- a Gray coding device configured to Gray code counter states of the counter signal to Gray coded counter states before transmission;
- and
- an inversion device configured to invert every second Gray coded counter state.
A method for processing a counter signal in an imaging system, the method comprising:
- coding counter states of the counter signal to Gray coded counter states before transmission;
- inverting every second Gray coded counter state of the Gray coded counter states to an inverted counter state;
- transmitting the inverted counter states;
- receiving the inverted counter states;
- inverting every second inverted counter state of the received inverted counter states to the Gray coded counter state;
- and
- converting the Gray coded counter states to binary code coded counter states.
