Formula Used

Image Frequency Bandwidth = Radio Frequency Bandwidth/Bandwidth Improvement
B_if = BW_rf/B_imp
This formula uses 3 Variables

Variables Used

Image Frequency Bandwidth - (Measured in Bit Per Second) - Image Frequency Bandwidth is a term used in radio communication to describe the range of frequencies around the image frequency that can interfere with the desired signal.
Radio Frequency Bandwidth - (Measured in Bit Per Second) - Radio Frequency Bandwidth is the range of frequencies that a radio signal occupies.
Bandwidth Improvement - Bandwidth Improvement is the reduction in the bandwidth of the received signal relative to the bandwidth of the transmitted signal.

STEP 1: Convert Input(s) to Base Unit
