Question 1 of 27070

Q

"The temperature coefficient of an x-cut crystal is negative":

🔍 Key Concepts

• Temperature coefficient (negative vs positive) and what it means on a graph of temperature vs frequency • How an oscillator crystal’s frequency changes when the crystal expands or contracts with temperature • Meaning of "negative slope": what happens to the dependent variable when the independent variable increases

💭 Think About

• If the temperature coefficient is negative, as temperature goes UP, what happens to the crystal’s operating frequency on a graph? • Then, if temperature goes DOWN, what happens to frequency when the slope is negative? Think about the opposite direction along the same line. • Compare each answer choice with the behavior you would expect from a line with a negative slope relating temperature (x-axis) and frequency (y-axis).

✅ Before You Answer

• Be clear which variable is on which axis: temperature vs frequency • Confirm what "negative temperature coefficient" means physically: frequency falls or rises with increasing temperature? • Check which option(s) match BOTH behaviors implied by a negative coefficient (what happens when temp increases AND when temp decreases).
