Describe the signal conditions for current-loop and RS-232C interfaces.

What is a data bus?

What is the difference between open-collector and tri-state output?

Use Multisim to draw a 555 oscillator with resulting output with \(t_{\text {low }}=2 \mathrm{~ms}\) and \(t_{\text {high }}=5 \mathrm{~ms}\).
