Draw the truth table and state the Boolean expression for the logic gate arrangement shown in Fig. 10. 2. State the Boolean logic expression for the logic gate arrangement shown in Fig. 11. 3. Devise a logic gate arrangement that provides the output described by the truth table shown in Fig. 12. 5 Tri-state logic Tri-state logic devices operate in a similar manner to conventional logic gates but have a third, highimpedance output state.

The 8-bit label field defines the type of data that is contained in the rest of the word. ARINC data words are always 32 bits and typically include five primary fields, namely Parity, SSM, Data, SDI, and Label. ARINC convention numbers the bits from 1 (LSB) to 32 (MSB). A number of different data formats is possible. 11 Basic ARINC 429 data word format (note the total length is 32 bits) Bits are transmitted starting with bit 1 of the label and the final bit transmitted is the parity bit. The standard specifies the use of odd parity (the parity bit is set to 1 or reset to 0 in order to ensure that there is an odd number of 1s in each transmitted word).
