Image Rejection Ratio in Analog Communications Formulas

Image Rejection Ratio is the ratio of the intermediate-frequency (IF) signal level produced by the desired input frequency to that produced by the image frequency. And is denoted by ρ. Image Rejection Ratio is usually measured using the Decibel for Noise. Note that the value of Image Rejection Ratio is always positive.
