The capacitor of given figureis initially charged to 40 V before the switch is closed. Write the expressions for the voltages vC and vR and the current iC for the decay phase.
Consider a particular communication system that the threshold is 1.5. If the signal energy falls below the threshold, the system is in the outage state. What is the outage probability P
Elements of electric motor drive systems - Four quadrant operation, Voltage control and current control
Design a digital notch filter to reject frequency 5 kHz completelyand to have a sharp recovery on either side of 5 kHz to a gain ofunity. The highest frequency to be processed is 20 kHz.
The 4:1 multiplexer function has four data inputs A,B,C,D, two select control inputs S1,S0 and a single positive-logic output Z that operates as follows. When S1,S0 = 00 gates A to Z; S1,S0 = 01 gates B toZ; S1,S0 = 10 gates C to Z
Sometimes the partial fraction expansion is not needed in finding the inverse Z-transform- instead the properties of the transform can be used. Consider the function F(z) = z+ 1/z^2(z - 1) a. Determine whether F(z) is a proper rational function as ..
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:
Point charge in a conducting shell. A point charge +q is located inside a very thin conducting spherical shell halfway between the center and the shell shown in Figure 5.46. Assume the conducting shell is at zero potential.
Create a block diagram of the electronics of the proposed vehicle. Include enough detail on each components and number of wires between each subsystem.
A separately excited dc motor, having a constant field current, accelerates a pure inertia load from rest. If the system is represented by an electrical equivalent circuit, with symbols as shown in Figure P16.2.16, express R, L, and C in terms of ..
Design a unity gain first order lowpass digital filter with a 3dB point at Fc=100Hz using Bilinear Transformation. The sampling rate is 1kHz. A first order analog filter is given by Ha(s)=θc/(s+θc) (a) What is the 3-dB frequency of the above analog ..
Consider a permanent-magnet dc-motor with the following parameters: Ra=0.35Ohms, La=1.5mH, Ke=0.5V/(rad/s), Kt=0.5Nm/A, and Jm=0.02kgm^2. The rated torque is 4Nm. This motor is supplies by a switch-mode dc-dc converter
A current filament carrying current of 15 A in z direction lies along the entire z-axis.Find H in cartesian coordinates at point (√20,0,4)and(2,-4,-4)
