🔍 Key Concepts

• Sample-and-hold function: what it needs to grab (sample) a voltage and then keep (hold) it unchanged for a period of time • Role of the capacitor in storing an analog voltage • Difference between minimum basic circuit and a more complete, practical circuit with extra buffers/amplifiers

💭 Think About

• Ask yourself: what physical component in electronics can "store" an analog voltage during the hold period? • What allows the circuit to connect and disconnect the input from that storage element at precise times? • Which answer choices include only what is absolutely necessary, and which ones add extra but non‑essential parts?

✅ Before You Answer

• Identify which choice(s) include a storage element suitable for holding a voltage (typically a capacitor). • Identify which choice(s) include a switching element to connect/disconnect the input (such as an analog switch). • Decide whether amplifiers and buffers are strictly required for a basic sample‑and‑hold, or if they are enhancements.
