More than one active input to an encoder will often produce an erroneous output. This problem may be partially overcome by the use of:
A) a priority encoder to ensure that when more than one input is active the output will correspond to the highest-numbered input.
B) an open-collector NAND gate whose inputs are connected to the decoder's outputs.
C) a priority encoder to ensure that when more than one input is active the output will correspond to the lowest-numbered input.
D) an additional encoder whose inputs are cascaded to the original decoder's outputs.
Question 2
The implementation of simplified sum-of-products expressions may be easily implemented into actual logic circuits using all ________ with little or no increase in circuit complexity.
A) OR gates B) multiple-input inverters
C) AND gates D) NAND gates
