Q

Advantage of crystal control over tuned circuit oscillators:

🔍 Key Concepts

• How a crystal oscillator works compared with an LC (inductor-capacitor) tuned circuit • Meaning of Q (quality factor), and how it relates to selectivity and losses • What determines frequency stability in oscillators (temperature, component drift, aging)

💭 Think About

• When people say crystal oscillators are preferred in radios for precise channels, which property are they usually talking about? • Does a quartz crystal generally have higher or lower Q than a typical LC tank circuit of similar size? • Think about which of the listed properties are true for crystals, and whether all of them must be true for choice D to be correct.

✅ Before You Answer

• Be clear on the difference between high Q and frequency stability—they are related but not identical concepts. • Ask yourself if compact size is a primary, defining advantage of crystals over tuned circuits, or just sometimes true. • Before picking an answer, verify whether every statement in choices A, B, and C is genuinely an advantage of crystal control in typical communication equipment.
