Question

An amplifier has 3 equal lower frequencies at 100 Hz, and 2 equal higher frequencies at 250KHz. determined the lower and higher dominant frequencies:

A. fₗ =100 Hz, fᵤ = 250KHz
B. fₗ =10 Hz, fᵤ = 25KHz
C. fₗ =128.7 Hz, fᵤ =392KHz
D. fₗ =392 Hz, fᵤ =392KHz

Answer 1

The lower dominant frequency is 100 Hz and the higher dominant frequency is 250KHz.

Step-by-step explanation:

In this question, we are given that an amplifier has 3 equal lower frequencies at 100 Hz and 2 equal higher frequencies at 250KHz.

The lower dominant frequency is determined by finding the average value of the lower frequencies, which is equal to 100 Hz.

The higher dominant frequency is also determined by finding the average value of the higher frequencies, which is equal to 250KHz.

Therefore, the correct answer is option A. f₃ = 100 Hz, fί = 250KHz
