Question

Additive signal noise may be characterised in many forms in the frequency spectrum. Briefly explain (and/or show on a simple sketch) what is meant by the terms white and pink flicker) noise. Sometimes, multiple sensors are sometimes used to overcome sensor noise. Briefly explain TWO (2) assumptions needed such that averaging the values from the multiple sensors is a valid mechanism to overcome this noise. Briefly describe one other strategy (other than "averaging" or "integration") for beating the noise in cases with multiple sensors.

Explanation / Answer

(A) white noise is nothing but a mixure of all frequencies in same amount. it s also known as random signal or random noise, which having equal intensity at different frequencies.the name "white noise" derived from the "white light".

pink noise is nothing but, a varient of white noise ,that has been filtered,to reduce the volume at each octave. the reason for doing this , to compensatefor increasing in the number of frequencies per octave.
