The data byte is a data processing circuits representation of the signal level on the detector element. It is converted to a weighted-binary number by passing through a ROM lookup-table which has been programmed to give the weighted-binary value of a gray-code address.
The data-path chip provides 3 major functions: It is applied to the header-register and the address-register in the chip.
It is also applied to the address lines of the gray-code converter. The combination of data processing circuits and address-register are shifted into the lut-address-register, a pipeline register which holds the current address while a new address may be arriving from the detector.

Compare the magnitude of two binary quantities 7 What does a encoder do? To anyone using BCD code, is equivalent to Pinout diagram data processing circuits 30 Example: An encoder outputs the binary value of the selected or active input.
An encoder performs the inverse operation of a decoder. An encoder accepts an active level on one of its inputs, representing digit, such as data processing circuits decimal or octal digits, and converts it to a coded output such as BCD or binary.
Encoders can also be devised to encode various symbols and alphabetic characters. The process of converting from familiar symbols or numbers data processing circuits a coded format is called encoding.
Data Processing Circuit
Data processing circuits parity means an n-bit input has an odd number of 1s. Voltage levels that do not change with time. Dynamic digital logic levels: Voltage levels that change with time.
It is the clock signal that advances the system logic through its sequences of steps.
Typical clock wave form used in a digital system. Clock need not to be the perfectly symmetrical waveform.
It could be simply data processing circuits of positive or negative pulses as shown in fig b The main requirement is that the clock be perfectly periodic, and stable. The basic timing interval is defined as the clock cycle time Clock cycle time — It is equal to one period of the clock wave form.

data processing circuits A change of state will either occur as the clock transition from low to high or as it transition from high to low. The low to high transition is frequently called the positive transition PT. A circuit that changes state at this time is said to be positive-edge-triggered The high to low is called the negative transition NT.
A data processing circuits that changes state at this time is said to be negative-edge-triggered. There are few exceptions — The operation of push button RESET by a human operator might result in an instant change of state that is not in synchronism with the clock.
