🔍 Key Concepts

• Frequency counters and how they measure signals • Difference between multiplying and dividing a frequency before measurement • Why high-frequency (HF) signals can be difficult for simple/low-frequency counters to handle directly

💭 Think About

• If you have a counter that can only handle up to a certain maximum frequency, what must you do to the incoming HF signal so the counter can still measure it? • Once the signal has been changed by this circuit, will the number the counter shows be higher or lower than the true signal frequency, and how would you recover the true value? • Think about the word "pre-scaler": does it suggest making a number bigger or smaller before measuring it?

✅ Before You Answer

• Identify whether a prescaler makes the input frequency larger or smaller before counting. • Check which choice correctly allows a low-frequency counter to work with a high-frequency input without being overloaded. • Eliminate any options that don’t involve changing the frequency value at all, or that change it in the wrong direction.
