Digital signal processing (AQA A-Level Physics): Flashcards

Output depends on current AND past inputs, not just current

Circuit that counts pulses in binary, controlled by clock signal

Clock Input - where clock pulses enter; each pulse increments

Up/Down Control: 1 = counts up, 0 = counts down

Master Reset - resets all outputs to 0 when signal is 1

$Q_0$ (Least Significant Bit)

$Q_3$ (Most Significant Bit)

$2^n - 1$ then resets to zero

Resets at any chosen number, not just powers of two
