What is the purpose of the local oscillator in an AM receiver?

The purpose of the local oscillator in an AM receiver is to convert the incoming radio signal to a lower frequency that is easier to amplify and demodulate. This is done through a process called heterodyning, in which the local oscillator signal is mixed with the incoming signal to produce two new signals at the sum and difference of the two original frequencies.

How to Calculate Local Oscillation Frequency of AM Receiver?

Local Oscillation Frequency of AM Receiver calculator uses Local Oscillation Frequency = Radio Frequency+Intermediate Frequency to calculate the Local Oscillation Frequency, The Local Oscillation Frequency of AM Receiver formula is defined as the frequency of a signal that is generated by the receiver and mixed with the incoming radio signal to produce the intermediate frequency. Local Oscillation Frequency is denoted by f_lo symbol.

How to calculate Local Oscillation Frequency of AM Receiver using this online calculator? To use this online calculator for Local Oscillation Frequency of AM Receiver, enter Radio Frequency (f_rf) & Intermediate Frequency (f_im) and hit the calculate button. Here is how the Local Oscillation Frequency of AM Receiver calculation can be explained with given input values -> 120 = 55+70.
