Counters – Exercise – 3

116. The MOD-10 counter is also referred to as a ________ counter.

(a) decade
(b) strobing
(c) BCD
(d) circuit

117. Many parallel counters use ________ presetting whereby the counter is preset on the active transition of the same clock signal that is used for counting.

(a) feedback
(b) synchronous
(c) ripple
(d) asynchronous

118. The technique used by one-shots to respond to an edge rather than a level is called ________.

(a) level management
(b) edge triggering
(c) trigger input
(d) edge trapping

119. In order to check the CLR function of a counter, ________.

(a) apply the active level to the CLR input and check all of the Q outputs to see if they are all in their reset state
(b) ground the CLR input and check to be sure that all of the Q outputs are LOW
(c) connect the CLR input to Vcc and check to see if all of the Q outputs are HIGH
(d) connect the CLR to its correct active level while clocking the counter; check to make sure that all of the Q outputs are toggling
