a. suggest a redesign of the common-emitter amplifier to increase the upper clipping voltage b. suggest a redesign of the common-emitter amplifier to decrease the lower clipping voltage c. why the base terminal of a BJT is never useful as an amplifier output D. explain why the collector terminal of BJT is never useful as an amplifier input
A new government law requires that the lead content of drinking water be less than 1.0 ppb. You are a safety engineer, and you have recently tested your companys drinking water using two methods. Method A gives a reading of 0.85 ppb

A fluid flows through a turbine at the rate of 45 kg/min. Across the turbine the specific enthalpy drop of the fluid is 580 kj/kg and the turbine loses 2100 kj/min in the form of heat energy. Determine the power produced by the turbine.
If we use a single mode fiber with 17 ps/nm/km dispersion for transmitting two different signals with two different wavelengths - 1550 and 1560 nm respectively -, what is the time delay between those two signals after 100 km?
What RF bandwidth must the radio link provide if the modulation is binary phase shift keying (BPSK)?
(a) find the value of a and K so that the relative damping ratio of the system is 0.5 and the rise time step response is approximately 1 s. (b) with the values of a and k found in previous question
How would you select the right components for the integrator and differentiator. What do you think would be the limiting factor in the component parameters, and in the input signal frequency
npn transistor has a CBJ with area 150 times that of EBJ. If Is= 5 x 10^-15 find the voltage drop across EBJ and CBJ when each is forward biased and conducting a current of 1mA. Also find the forward current each junction would conduct when forwar..
Design a circuit for easy connection between a TTL gate and a TRIAC that uses a buffer transistor between the output port of the gate and the TRIAC. (a) In the 1st and 4th quadrants, (b) In the 2nd and 3rd quadrants.
In the movement of a robot arm, the arm is commanded to go from position 1 to position 5. Discuss the rise time, the overshoot, the settling time, and the steady-state error as it applies to the movement of a robot arm
Considera causal LTI system. When the input to the system is u(t-5) the unilateral Laplace transform of the output is Y(s)=(e^-6s -e^-9s)/s^2 Determine and sketch the output of the system when the input is x(t) shown below:
