The L-point averaging filter is a lowpass filter. Its passband width is controlled by L, being inverselyproportional to L. It is also possible to create a filter whose passband is centered around some frequencyother than zero. One simple way to do this is to define the impulse response of an L-point FIR as:

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
