A masking circuit triggered by the signal to be measured inhibits the signal
to be measured, thus ignoring the signal of interest for the period of masking
time after being triggered by the signal.
3-3-9. Masking
Consider measuring Tx of the signal shown below. When MASK is OFF,
Tx' is measured. Setting the masking time to Tm will enable the measure
ment of Tx.

Masking can be utilized in the FREQ. B, PERIOD B, T.l. A ->B, RATIO
A/B, and TOT. A functions.
