A silver bar having the following characteristics:Length = 10 cmConstant cross section of area = 1 cm2Density = 10.6 g/cm3Thermal conductivity = 1.04 cal/(cm sec )Specific heat = 0.056 cal/(g )is perfectly insulated laterally, with ends kept at 100 for a long time.Then at some instant, call it t = 0, the temperature at x = L is suddenly changed to 0 and kept at 0 , whereas the temperature at x = 0 is kept at 100 .Determine the temperature in the middle of the bar and evaluate it at t = 1, 2, 3, 10, 50 sec. First guess, and then calculate. Also, plot the temperature expression vs. time from t = 1 to 50 sec using Excel .
A student project is required to be portable and hand held. It requires 6 V DC power at a current of 150 mA. The batteries for the power supply must last for a minimum of 7 hours of continuous operation.
A three-point symmetric moving average filter, referred to as a weighted moving average is of the form \(y[n]=b(ax[nu22121]+x[n]+ax[n+1])\) (a) Determine as a function of a and b the frequency response \(H(e^{j\omega})\) of this system.
