We have two noise sources and an RMS voltmeter. We measure the RMS values and they are 3V and 5V. We would like to determine the correlation coefficient but we have an adder only. Putting the two noise sources in series produces a noise with 4V effective value.

a. Calculate the crosscorrelation coefficient at this arrangement.

b. Both uncorrelated noises must have 1 V rms amplitude.

Ahot wire operates at a temperature of 200°c while the air temperature is 20°c. the hot wire element is a tungsten wire of 5 um diameter and 2 mm in length. plot using excel current, heat transfer and heat generated by the wire for air velocity varying from 1-10 m/s in steps of lm/s? matlab the sensor voltage output, resistance, or assume nu 0.989 re033pr13 take air properties at tr (200°c20°c)/2 = 110°c properties of tungsten: c 0.13 kj/kg.k 3 p 19250 kg/m k (thermal conductivity) = 174 w/m.k
