-Select the sequence for the counter in Figure 7- 1 that best describes its operation.
A) Counter clears: starts counting pulses when the sample pulse goes HIGH; stops counting when the sample pulse goes LOW. Clear pulse clears the counter by transferring its contents into the decoder/display unit.
B) Counter clears: starts counting pulses when the sampling pulse goes LOW; stops counting when the sampling pulse goes LOW; stops counting when the sample pulse goes LOW and displays the final count.
C) Counter clears: starts counting pulses when the sampling pulse goes HIGH; displays the counts as they occur and stop counting when the sampling pulse goes LOW. Count is displayed until the counter is cleared.
D) Counter clears: starts counting pulses when the sample pulse goes HIGH; stops counting when the sample pulse goes LOW. The LOW sample pulse activates the display and the final count is displayed.
