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.
