Show that a Miller integrator implemented with an op amp with open-loop gain A0 has a low-pass STC transfer function. What is the pole frequency of the STC function? How does this compare with the pole frequency of the ideal integrator? If an ideal Miller integrator is fed with a -1-V pulse signal with a width T=CR, what will the output voltage be at t=T? Assume that t=0, v0=0. Repeat for an integrator with an op amp having A0=1000.

A silica fiber has an outer diameter of 125 micro meter. What is the total volume of silica for a 1-km length? This fiber is wound on a spool whose unloaded diameter is 20 em. The spool height is 10 em. Compute the diameter of the fully loaded spo..
A 10-bit unipolar ADC with a reference of 5.00 F and a 44 micro seconds conversion time will be used to collect data on time constant measurement. Thus, the input will be of the form V (t) = 4(1-e^t/T) . What is the minimum value of T
A dc machine is rated 5 hp with V_f = 240 V, V_a = 240 V, r_a = 0.63 ohms, and L_AF = 1.8 H. At rated condtions w_r = 127.7 rads/s and the total resistance of the field circuit is 240 ohms. a) Calculate the rated armature current.
