Question
**Problem #08** For the 4-bit parity generator shown, determine the output. Is this circuit generating even or odd parity? ### Explanation: The image shows a 4-bit parity generator circuit. It includes: 1. **Input Signals (A0, A1, A2, A3):** These are the four input bits that are used to generate the parity bit. The signals are aligned vertically and are presented in a waveform format, indicating the bit value over time. 2. **Bit Time:** Indicates the duration during which each bit is active. This timing diagram helps in understanding the synchronization of inputs. 3. **Logic Gates:** - Two XOR (exclusive OR) gates are illustrated. - The first XOR gate takes two inputs from the waveform and produces an output. - The second XOR gate takes the output from the first XOR gate and another input from the waveform to produce the final parity output. ### Parity Determination: - **Even Parity**: The parity bit is set such that the total number of 1's in the set (including the parity bit) is even. - **Odd Parity**: The parity bit is set so that the total number of 1's in the set is odd. Based on the description, the circuit seems to be generating even or odd parity depending on the configuration and logic of the XOR gates, which is observed by following the flow of XOR operations and checking the parity condition.
