Amplifier repeater
LNB stands for Low Noise Block. This device amplifies the weak incoming signal from the satellite and converts it to a signal that is usable by the television.
A repeater that does not distinguish between noise and signal; it amplifies both.

any signal, be it be noise is composed of sinusoids...so when one differentiates sinWt with respect to time it becomes WcosWt ...hence the signal gets multiplied by W..
A Low Noise Block Down Converter (LNB) is an active device. It amplifies the weak signals received from satellite dishes and converts them from a higher frequency to a lower frequency for easier processing. The active components, such as amplifiers and oscillators, are essential for its function, differentiating it from passive devices that do not provide amplification or signal processing.

The noise reduction ratio (NRR) measures how much background noise is reduced by a device or process, while the signal-to-noise ratio (SNR) compares the level of the desired signal to the level of background noise present in audio processing.
In logarithmic quantization, one does not quantize the incoming signal but log of it to maintain signal to noise ratio over dynamic range. Dr Inayatullah Khan
Signal-to-Noise Ratio (SNR) measures the quality of the signal compared to the level of background noise, indicating how clear the audio is. Noise Reduction Rating (NRR) quantifies how much external noise is reduced by a device, such as headphones or earplugs, to improve the listening experience.
An autocorrelator is a device which modifies a signal with a delayed copy of itself in order to detect any periodic signal hidden in the noise.
Signal to noise ratio is a measure of signal strength to the background noise. Engineers use the signal to noise ratio to improve digital signal processing.
Noise signal is any signal which interferes with the main signal and does not give any important information.Signal should always be twice to that of noise.
