Question

For a square wave signal with a frequency of 10 KHz, calculate the output frequencies for Mod 2, Mod 4, and Mod 10 counters.

• A. 20 KHz, 40 KHz, 100 KHz
• B. 50 Hz, 25 Hz, 0.1 Hz
• C. 50 KHz, 25 KHz, 10 KHz
• D. 5 KHz, 2.5 KHz, 1 KHz

Hint:

To calculate the output frequency of a Mod counter, simply divide the input frequency by the modulus of the counter.

Answer 1

The Correct Option is D

For Mod counters, the output frequency is the input frequency divided by the modulus of the counter: - Mod 2: \( \frac{10 \text{ KHz}}{2} = 5 \text{ KHz} \) - Mod 4: \( \frac{10 \text{ KHz}}{4} = 2.5 \text{ KHz} \) - Mod 10: \( \frac{10 \text{ KHz}}{10} = 1 \text{ KHz} \) Therefore, the correct answer is option (4).
