- Signal to Noise Ratio: Definition Wiener Filter Calculation
You need to know how the signal and the noise look like at the filter input and calculate what they will be at the output Usually a signal has a narrow spectrum, while the noise has a broad (almost flat) spectrum Apply a filter to that and see how much power is in signal and how much is in noise at the output of the filter
- What is meant by signal-to-noise ratio? - Physics Forums
Well, the signal-to-noise ratio is a number that gives a numerical indication of how well the signal is getting through, regardless of the reason You can have mechanical devices creating noise (poor shielding on wires), natural phenomena (such as lightning) you can have interference (from powerful signals nearby) and all sorts of other things
- Signal to Noise Ratio Calculation in Decibels: How to Simplify with . . .
(b) If the signal level from the aerial is 5 dBmV and the input noise level is 20 dBμV, calculate the signal-to-noise ratio on the output of the amplifier Values: Bandwidth 40–862 MHz Gain 20 dB Noise Figure 6 dB Max Output 85 dBV Input Impedance 75Ω Output Impedance 75Ω Relevant Equations:: SNR=20Log(Vs Vn) SNR=10Log(Ps Pn)
- Signal strength and DNR (signal to noise ratio) - TiVo Community
The system was working so I left their splitters in place In checking my signal strength it was 100% and since the Tivo diagnostic screen does not read above 100% it could again be pulling in a signal much higher and hotter than 100% I'm the last house on my street and Spectrum says that can cause a hot signal

- Attenuators dont affect the SNR | TiVo Community Forum
It is the "Signal to Noise Ratio", a measure of signal quality and should be as high as possible 38 db is good An attenuator reduces both the signal and the noise and will not affect this value as long as the signal strength is not too strong or weak If the signal is too strong to begin with than an attenuator can increase the SNR
