Use MATLAB to record 10 seconds of your speech using a sampling frequency of 8000Hz(see: audiorecorder in MATLAB and record in Octave). Explain what is happening atthe hardware level when you record your speech (a continuous signal) to store it in yourcomputer (i. e., explain the steps involved in the sampling and quantization process).

Consider a 1.2 meter high and 2 meter wide glass window whose thickness is 6 mm and thermal conductivity is 0.78 w/m °c. the room temperature is maintained at 24 °c, while the outdoor temperature is -5 °c. the convective heat transfer coefficients on the inner and outer surfaces of the window are 10 w/m2 °c and 25 w/m2 °c respectively. (a) draw the thermal resistance network, etermine the steady rate of heat transfer t e glass window (c) determine the temperature of the inner surface of the window
