Intermediate Frequency Solution

Follow our step by step solution on how to calculate Intermediate Frequency?

FIRST Step Consider the formula

f im = (f lo - F RF)

Next Step Substitute values of Variables

∴

f im = (125Hz - 55Hz)

Next Step Prepare to Evaluate

∴

f im = (125 - 55)

LAST Step Evaluate

∴

f im = 70Hz
