Intermediate Frequency Solution

STEP 0: Pre-Calculation Summary

Formula Used

Intermediate Frequency = (Local Oscillation Frequency-Received Signal Frequency)
f_im = (f_lo-F_RF)
This formula uses 3 Variables

Variables Used

Intermediate Frequency - (Measured in Hertz) - Intermediate Frequency is a frequency to which a carrier wave is shifted as an intermediate step in transmission or reception.
Local Oscillation Frequency - (Measured in Hertz) - Local Oscillation Frequency is that frequency which is used by electronic oscillator along with a mixer to change the frequency of a signal.
Received Signal Frequency - (Measured in Hertz) - Received Signal Frequency is that frequency which is obtained at the receiver end of a Radio Channel.

STEP 1: Convert Input(s) to Base Unit

Local Oscillation Frequency: 125 Hertz --> 125 Hertz No Conversion Required
Received Signal Frequency: 55 Hertz --> 55 Hertz No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

f_im = (f_lo-F_RF) --> (125-55)

Evaluating ... ...

f_im = 70

STEP 3: Convert Result to Output's Unit

70 Hertz --> No Conversion Required

FINAL ANSWER

70 Hertz <-- Intermediate Frequency

How do you determine intermediate frequency?

Intermediate frequency (IF) should be carefully chosen as High IF results in poor selectivity and therefore poor rejection of adjacent channels. - High IF results in problems in tracking of signals in the receivers. - Image frequency rejection becomes poor at low IF or if very high.

How to Calculate Intermediate Frequency?

Intermediate Frequency calculator uses Intermediate Frequency = (Local Oscillation Frequency-Received Signal Frequency) to calculate the Intermediate Frequency, Intermediate Frequency is a frequency to which a carrier wave is shifted as an intermediate step in transmission or reception. Intermediate Frequency is denoted by f_im symbol.

How to calculate Intermediate Frequency using this online calculator? To use this online calculator for Intermediate Frequency, enter Local Oscillation Frequency (f_lo) & Received Signal Frequency (F_RF) and hit the calculate button. Here is how the Intermediate Frequency calculation can be explained with given input values -> 70 = (125-55).

FAQ

What is Intermediate Frequency?

Intermediate Frequency is a frequency to which a carrier wave is shifted as an intermediate step in transmission or reception and is represented as f_im = (f_lo-F_RF) or Intermediate Frequency = (Local Oscillation Frequency-Received Signal Frequency). Local Oscillation Frequency is that frequency which is used by electronic oscillator along with a mixer to change the frequency of a signal & Received Signal Frequency is that frequency which is obtained at the receiver end of a Radio Channel.

How to calculate Intermediate Frequency?

Intermediate Frequency is a frequency to which a carrier wave is shifted as an intermediate step in transmission or reception is calculated using Intermediate Frequency = (Local Oscillation Frequency-Received Signal Frequency). To calculate Intermediate Frequency, you need Local Oscillation Frequency (f_lo) & Received Signal Frequency (F_RF). With our tool, you need to enter the respective value for Local Oscillation Frequency & Received Signal Frequency and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
