For the circuit of given figure:
a. Determine the time constant of the circuit when the switch is thrown into position 1.
b. Find the mathematical expression for the voltage across the capacitor after the switch is thrown into position 1.
c. Determine the mathematical expression for the current following the closing of the switch (position 1).
d. Determine the voltage vC and the current iC if the switch is thrown into position 2 at t = 100 ms.
e. Determine the mathematical expressions for the voltage vC and the current iC if the switch is thrown into position 3 at t = 200 ms.
f. Plot the waveforms of vC and iC for a period of time extending from t = 0 to t = 300 ms.
In designing a low-pass filter for an audio system, the filter stop band attenuation must be at least 40 dB at a frequency that is 2 times the passband frequency. The attenuation in the passband must be less than 1 dB.
A minority voting circuit makes a decision based on the minority of votes. The logic receives THREE inputs x, y, and z.Together, these input variables are the binary representation ofthe number of members who vote "yes" out of 7 total members.
applying the bandpass sampling theorem to a signal of bandwidth w around a certain frequency f0 what happens to the
Suppose we have a sensor that has one terminal grounded. The sensor is to be connected to a DAQ board in a computer 5meters away. What type of amplifier should we select? To mitigate noise from electric and magnetic fields, what type of cable sho..
Write an assembly program that converts a string with four characters into an unsigned 16-bit integer. For example, a string "A23F" should be converted into an unsigned integer. Assume that the input string consists of only valid characters (0,... ..
The potentiometer extends between positions 1.9 cm and 54.6 cm on the scale. The voltage read by the DMM is 1.000 V and the current read the by DMM is 42mA. What is the resistance per unit length of the nichrome wire
You need to drill a 20. mm hole in a piece of stainless steel. The drill feed is 0.10 mm/revolution and its rotational speed is 400. RPM.
Develop a logic circuit whose output is high when the input has had three consecutive ones to the input. Overlapping threes are allowed. (e.g., x=011110110 then the output z=000110000 assuming starting state was 0).
Determine the types of load impedances/admittances that can be matched with the two single-element networks shown below.
Transfer function : key informaiton, A linear time-invariant discrete-time system is excited by the input x[n] = d[n] + 2u[n-1] (d represents δ(delta)). The resulting output response with zero initial conditions is y[n] = ((0.5)^n * u[n]). De..
