1. Design a single OP AMP amplifier with a voltage gain of -1000 and an input resistance greater than 5 kΩ using standard 5% resistance values less than 3:3 MΩ.
2. Design an OP AMP amplifier with a voltage gain of 4 using only 15-kΩ resistors and one OP AMP.
3. Using a single OP AMP, design a circuit with inputs v1 and v2 and an output vO = v2 - 5v1. The input resistance seen by each input should be greater than 1 kΩ.
The circuit connected in series
The transmitting fiber has a core diameter of 80µm and the receiving fiber has a core diameter of 110µm. The transmitting fiber has n1=1.46 n2=1.40 and the receiving fiber has n1=1.48 and n2=1.46. Will this joint meet the loss restrictions
a test on an 80 w fluorescent lamp circuit gave the ff. results when connected to a 50 hz mains supply. calculate the
Assume the triac of an ac output module fails in the shorted state. How would this affect the device connected to this output
A certain appliance has a potential difference of 100volts while getting a current of 1.5 amperes. Calculate the rate at which energy is changing in this appliance.
Assume that Load 1 is Y-connected. What are the phase voltage and currents in that load? Solve in per unit and convert to real volts and amps
Two dielectric media with dielectric constants ε1 and ε2 are separated by a plane boundary at x = 0, A point charge Q exists in medium 1 at distance d from the boundary. a - Verify that the field in medium 1 can be obtained from Q and an image char..
The addition of impurities is known as doping. When elements with a valance number of 5 (pentavalent impurity) are added, the silicon or germanium is referred to as N-type; if elements with a valance number of 3 (trivalent impurity) are added, the si..
The factorial n! of a positive number (integer) is defined by: n! = n(n-1)(n-2)...3*2*1, where 0! = 1. Write a user difned fuction that calculates the factorial n! of a number. For the function name and arguments use y = fact(x)
The controlled variable in a closed-loop system is the direction of a robot arm. Initially, it is at 50o; then it is commanded to go to 15o. When the error is 10o for the first time, what is direction of the robot arm
Consider the following second order transfer function: G(s) = 2/s2+0.4s+1.. Use MATLAB Simulink software to investigate the performance of APD controller with a fixed proportional gain of Kp=0.2. Demonstrate the effect of changing the value of Kd ..
