What are some of the applications of coupling factor in receivers?
Coupling factor is an important parameter of a receiver, as it affects its performance in a number of ways, including image frequency rejection ratio (IMRR), noise figure, and sensitivity.
Image rejection: The image frequency is a frequency that is reflected around the local oscillator frequency and can interfere with the desired signal. The coupling factor can be adjusted to optimize the IMRR of the receiver, which is the ability of the receiver to reject the image signal. This is important for applications where the image signal is likely to be strong, such as in urban areas.
Sensitivity: The sensitivity of a receiver is its ability to detect weak signals. The coupling factor can be adjusted to improve the sensitivity of the receiver. This is important for applications where the incoming signal is likely to be weak, such as in rural areas.
How to Calculate Coupling Factor of AM Receiver?
Coupling Factor of AM Receiver calculator uses Coupling Factor = (Image Frequency/Radio Frequency)-(Radio Frequency/Image Frequency) to calculate the Coupling Factor, The Coupling Factor of AM Receiver formula is defined as a measure of how much of the incoming signal is coupled to the local oscillator. It is typically expressed as a percentage, with a higher coupling factor indicating more energy transfer. Coupling Factor is denoted by cf symbol.
