Boron donor atome at a concentration of 10^15 cm^-3 are distributed uniformley throughout a silicon sample. The sample is then also doped with 6*10^15 cm^-3 of phosphorous. calculate the position of the Fermi level
1. Determine the minimum value of gain K when Gc(s)=K, so that the steady-state effect of a unit step disturbance Td(s)=1/s is less than or equal to 5% of the unit step (y(inf)=0.05). 2. Determine whether the system using the gain of part 1 is stab..
Consider the 1D system whose input-output equation is given by g(x) = f(x)*f(x), where * denotes convolution. a) Write an integral expression that gives g(x) as a function of f(x). Hint: Convolution definition
Summarize when and why it is important to use the "50Ω"termination setting on the function generator (with thecorresponding 50Ω terminator in the circuit, of course). In which situations would this not be necessary.
An AM modulator operates with the message signal m(t) = 6cos(10πt) - 4sin(30πt) with unmodulated carrier: 50cos(30πt) and index of 0.1 Write the equation for mn(t) the normalized signal with minimum value of -1.
