A certain silicon sample has NA = 5.01 X 1016cm-3and ND = 5.02 x 1016 cm-3. Given µn= 1200, and µp= 400cm2/V-s, determine a) The conductivity b) Repeat part (a) if NA =1017 and ND = 1.1 x 1017 cm-3. Use the mobilities of part (a).
Starting from rest, a 4.70-kg block slides 2.10 m down a rough 30.0° incline. The coefficient of kinetic friction between the block and the incline is k = 0.436. (a) Determine the work done by the force of gravity.
Let x[n] = [1,2,3,2,1] with arrow under 3 and y[n] = [2,1,0,-1,-2] with arrow under 0. a) using scanning operation, determine and plot correlation sequence between two signals. b) Determine and plot correlation coefficient.
a carrier wave is frequency-modulated using a sinusoidal signal of frequency fm and amplitude Am. (a) determine the values of the modulation index beta for which the carrier component of the fm signal is reduced to zero. see the appendix for calcu..
