Signal to noise ratio is the difference between the noise floor and the reference level.
The two are totally unrelated. Classes means categories. It is also used as a programming concept. Interference is a phenomenon that happens when two waves meet.
the frequency difference between the transmitter and the receiver without any noise or distortion
Thermal noise
SINR - Signal to Interference and Noise Ratio CINR - Carrier to Interference and Noise Ratio difference between those to is difference between carrier and signal carrier is signal who doesn't "carry" any information . it must be modulated( by phase,freq or amplitude) and those changes convey information. carrier is unmodulated signal signal is defined as useful signal which carries information SINR is power of signal to power of interfenence and noise ratio
Interference and noise are distinguished the same way in all situations not just optical communication. Noise is caused by random thermal effects or statistical effects to to the randomized distribution of electron flow. Interference is due to a system being sensitive to external perturbation, due to weather, dust, vibration etc.
No. Fiber is immune to electrical interference; there is no cross-talk between signals in different cables and no pickup of environmental noise.
Current measures flow of charge. Interference is something that gets in the way.
a noise of a computer is lower than atelivision
Music can be coined as structured, organized noise.
They dont make noise only interference
the difference between voice and noise is the voice is somebody speaking and it is smooth and mellow and noise means loud and mad if you think say noise in your head when you say noise you just no what it means loud big and it could mean danger as well.
Twisting wires is done the prevent electromagnetic interference between the circuits(known as noise).

A loud noise...
Is that the signal interference + noise ratio?
