and will register a true if it happens to fully contain an equivalent of a full
multivibration pulse.

(a) What is the probability of sampling a true? A false? (ANS. 0.1 %, 99.9 %)
(b) Repeat the above, only assume sampling is synchronized with f 0 to begin at
1 ms and to end at 1 s. What is the probability of a false at f 0 ? (ANS. 0)
7. Derive, with reference to sketched waveforms, that P

¼ τ f x 100 %.

Toggle Circuits Using Simulated Qubits

8. State the differences between a toggle and a data latch. (HINT: a data latch
holds the truth value applied to it until it is overwritten or cleared, after which
the original truth value is lost forever; by keeping track of the number of
toggles, past truth values in a toggle are never lost)
9. Draw the given circuit for Excitory/inhibitory toggling. Explain how it is
started and how it is stopped.

(a) Why does it start?
(b) Why does it stop?

10. Draw the circuit for the NAND/XOR toggling and explain how it is started and
how it is stopped.

(a) Why does it start?
(b) Why does it stop?

Qubit Sphere

11. Approximately locate

(a) The vector with zero phase and 75 % probability for a true.
(b) The vector with 180 phase and 75 % probability for a true.
(c) Why does phase have no effect on the measured probability?
