Consider the dynamic system as represented by the differential equation below and shown in Figure 5.40.
This is a rod attached to a fixed end. Assume that the rod can be represented as a rotational spring with spring constant k, and the mass of the rod is concentrated and modeled by the moment of inertia J.
1. Draw the block diagram representing the system.
2. If the torque is represented as a unit step signal, what is the angular rotation in radians?
3. Find the final and the initial values for θ (t).
Design an XOR gate using standard CMOS logic and with pass-transisitor logic and determine the number of transistors (NMOS and PMOS) required for each implementation.
Sketch a Bode plot for the frequency response of a High-pass R-C filter where R=470ohms and C=0.047uF. Draw the circuit, calculate the actual cutoff frequency, and calculate the dB level at one-half the critical frequency and twice the critical fr..
Questions 1. Describe what is meant by the voltage gain of an amplifier 2, What is the primary purpose of a coupling capacitor ub transistor amplifiers?
Find the change in currents due to change of voltage by (a) 5mv, (b) -10mv, (c) 15mv using small signal model and exponential model of diode with n= 1 and biased at 2mA.
Design a three-line to eight-line (3-to-8) decoder which will decode three input variables into eight outputs. An application of this decoder is a binary-to-octal conversion, where the input variables represent a binary number and the outputs repr..
Why does the distortion level of the primary current waveform change when a dc bias is applied - explain why the voltage waveform measured on the oscilloscope is not dc biased.
A gas of density 1.83kg/m^3 and a viscosity of 1.5 x 10^-5 Pa.s is pumped through the tower. The volumetric flow rate of the gas at the entrance is 20 m^3/hour. a. Calculate the pressure drop at the exit of the packed bed.
Examples of element characteristics:- Strain gauge. - Copper-constantant. thermocouple. - Accelerometer. - Give a well labeled diagram of the above.
Calculate the dc voltage that should exist across R2 without the Voltmeter present. Calculate the dc voltage that would be measured across R2 using a 10 kΩ/V analog voltmeter set to the 10-V range.
The real and imaginary parts of the product are similarly represented, but with 8 prebinary-point and 24 post-binary-point bits. The complex multiplier is subject to constraints that strongly limit the circuit area.
What is the final angle of the shaft?
A rectangular, 20 mA current pulse of 3 ms duration is applied to a 5 μF capacitor (i-0, t ≤ t ≤ 3ms; i-0, t > 3ms). Find the resultant capacitor voltage v. Assume the capacitor is uncharged for t
