Held Value Feeds Threshold - Electronic Circuits V: Front-End Conditioning and Gain Contracts Step by Step

The next stage reads the held voltage, not the later input. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

highlighted = computed this step

The held value is the next input

The held output is 4 volts, so the next stage sees that value.

V_{\text{next}} = 4\ \text{V}

The held value crosses the upper threshold

The held value of 4 volts is above the upper threshold of 3 volts.

4\ \text{V} \ge 3\ \text{V}\Rightarrow \text{HIGH}
