The Decoding Gates for Asynchronous Counters May Have "Glitches" on Their

Multiple Choice

The decoding gates for asynchronous counters may have "glitches" on their outputs because:

A) the flip- flops change states one at a time and erroneous counts may occur prior to the time all FF outputs have stabilized.
B) the flip- flops all change states at the same time but t_pd may vary slightly for each FF thereby producing glitches.
C) the flip- flops change states one at a time; therefore no change for producing a glitch will ever exist.
D) the flip- flops all change states at the same time.
