Sample Window Total Three-Row Scan - Electronic Circuits IX & X: Feedback Control and Sampled Conversion Step by Step

Clock period and sample count multiply into the covered sample window.

Clock period and sample count multiply into the covered sample window. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

highlighted = computed this step

Four samples at two seconds cover eight

A clock period of 2 s across 4 sample cells covers 8 s.

4\cdot2\ \text{s}=8\ \text{s}

Six samples at the same period cover twelve

A clock period of 2 s across 6 sample cells covers 12 s.

6\cdot2\ \text{s}=12\ \text{s}

Halving the period halves the same-count window

A clock period of 1 s across 6 sample cells covers 6 s.

6\cdot1\ \text{s}=6\ \text{s}
