Disadvantages of Noise Factor
let us see the disadvantages of noise factor:
- An increased Noise factor indicates a degraded signal. Systems that have higher noise factor indicate that the quality of the signal is poor mainly due to enhanced noise.
- Calculation of noise factor can be complex sometimes. This is mainly complex in case of cascaded systems because interconnected components can complicate the calculations.
- Noise Factors method becomes unreliable because noise factor is temperature sensitive. With an increase in temperature, the Noise factor increases which impacts the whole system by degrading its performance.
- Noise Factor can only provide information about certain components. Due to lack of versatility it can be a challenging task to obtain system information from noise factor.
- Noise Factor is a theoretical concept therefore it might not accurately describe the real-world situation. Real-world involves certain important factors like environmental conditions which are ignored while calculating noise factor.
What is Noise Factor?
Often while dealing with signals in electronics and communication systems, we encounter distortion in signals due to noise. Noise is an unwanted disturbance that can attenuate our signal making it difficult to obtain the original signal. In this article, we will study the noise factor which is an important instrument used for measuring the quality of signals.
Later, we will understand the work behind calculating the noise factor. Through a diagram, we will also see the formula used for calculating noise factor with a physical understanding of the formula. Some solved examples have been provided to enhance the understanding of readers about the topic. We will look at the advantages, disadvantages, and applications of noise factors in the real world. In the end, we will conclude the article with some frequently asked questions that readers can refer to.
