Question
**Determining Inputs for a BCD Priority Encoder with Active-LOW Outputs** The following scenarios illustrate which inputs can be determined and which are unknown for a Binary-Coded Decimal (BCD) priority encoder with active-LOW outputs. The outputs are presented as sequences of binary digits where each digit corresponds to a specific input channel. a. \( Q_3Q_2Q_1Q_0 = 0111 \) b. \( Q_3Q_2Q_1Q_0 = 1110 \) c. \( Q_3Q_2Q_1Q_0 = 1100 \) d. \( Q_3Q_2Q_1Q_0 = 1111 \) Each line represents the state of the output bits \( Q_3, Q_2, Q_1, \) and \( Q_0 \). In a priority encoder with active-LOW outputs, a '0' indicates the presence of a signal, while a '1' indicates no signal. The binary codes shown will determine which inputs are activated and prioritized.
