Age 15Explain it to a 15-year-oldConnect it to the formula
Image-rejection ratio in decibels compares desired-sideband power with unwanted image power. This page isolates positive image power and verifies it in the original relationship. The rule is b=a/10^(c/10). Its input values are image-rejection ratio in decibels, positive desired-sideband power, and the main result is positive image power. For example: positive desired-sideband power=10000 and positive image power=1 produce image-rejection ratio in decibels=40.
CollegeExplain it at college levelState the model precisely
This calculator evaluates the stated image-rejection power ratio in decibels: solve positive image power relation over the valid real-number domain stated below. The implemented relation is b=a/10^(c/10), evaluated from image-rejection ratio in decibels, positive desired-sideband power to produce positive image power. Image-rejection ratio in decibels compares desired-sideband power with unwanted image power. This page isolates positive image power and verifies it in the original relationship. Measure both powers with the same bandwidth and calibration.
Inputs and valid domain
- image-rejection ratio in decibels must be a finite real number.
