Objective
Count 16 clock pulses with a 4-bit synchronous counter and read the binary count on four probes.
Procedure
- Run and read Q3 Q2 Q1 Q0 after each rising edge.
Theory
Q0 toggles every clock, Q1 every 2nd, Q2 every 4th, Q3 every 8th: the outputs count 0000 … 1111 and wrap round. Each output is the clock divided by 2, 4, 8, 16.
Questions to answer
- What is the modulus of this counter?
Components used
4-bit binary counter, Clock source, 4 × Logic probe / LED, Logic switch
About the model
Ideal wires; component models as listed in the catalogue (no parasitics, no temperature drift). Built without a breadboard so the schematic stays readable.
