FAQ

What is the Rejection Ratio?

Rejection Ratio is the ratio of the gain at the signal frequency to the gain of the image frequency in a single-tuned circuit. Rejection Ratio is usually measured using the Decibel for Noise. Note that the value of Rejection Ratio is always positive.

Can the Rejection Ratio be negative?

No, the Rejection Ratio, measured in Noise cannot be negative.

What unit is used to measure Rejection Ratio?

Rejection Ratio is usually measured using the Decibel[dB] for Noise. Neper[dB], MilliDecibel[dB] are the few other units in which Rejection Ratio can be measured.
