1. What is the bandwidth of an amplifier if the risetime is 0.25 μs?
2. The upper cutoff frequency of an amplifier is 100 kHz. If it is square-wave tested, what would the risetime of the amplifier output be?
Two transistors have EBJ areas as follows: AE1 = AE1 = 400μm x 400μm and AE2 = 0.4μm x 0.2μm. If the two transistors are operated in the active mode and conduct equal collector currents
The windings of high-current electromagnets are often made of copper pipe. The current flows in the walls of the pipe, and the cooling water flows in the interior of the pipe. Suppose the copper pipe has an outside diameter of 1.2 cm and inside di..
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
A compact disc (CD) records audio signals digitally by usingPCM. Assume that the audio signal bandwidth equals15kHz. a) If theNyquist samples are uniformly quantized into L = 65536 levels andthen binary-coded
If the attenuation coefficient for the wave in equation E =Eoe-αzsin(ωt - kz) has the value 2x 10-5 cm-1, compute the power loss in dB for1 km. Compute the fractional loss for 1 km.
Show that the electric field at a point of the model is nin-2 times the field at the corresponding point of the actual system.
Consider a situation where two microcontrollers are connected with a CAN network. Computer 1 generates 8-bit data packets that must be sent to Computer 2, and Computer 2 generates 8-bit data packets that must be sent to Computer 1
