he acid/alkaline balance of a fluid is measured by the pH scale. The scale runs from 0 (extremely acid) to 14 (extremely alkaline), with pH 7 being neutral. A pH electrode is a sensor that produces a small voltage that is directly proportional to the pH of the fluid in a test chamber.
For a certain pH electrode, the proportionality factor is 50 mV=pH. A preamplifier is needed to interface this sensor with a variety of laboratory instruments.
The output of the preamp must be 1 V when the sensor is immersed in a test solution with pH = 4 and 1:75 V when it is immersed in a solution with pH = 7. Design an amplifier to meet these requirements.
Objective: Develop a digital logic circuit utilizing the skills gained in EE202 to create a circuit capable implementing a Hamming error correction code. Description: The data transmitted through you're the system is stored in 8 bit (1 byte) words. I..
An 80 kHz sinusoidal voltage has zero phase angle and a maximum amplitude of 25 mV. When this voltage is applied across the terminals of a capacitor, the resulting steady state - state current has a maximum amplitude of 628.32 microamps.
Implement switching function of 4 variables H(A,B,C,D)= AB'+BC+A'CD using a 4 to 1 Multiplexer and any number of 2 to 1 multiplexer. One can select any 2 variables (for example, AB or CD) as select inputs of one 4 to 1 multiplexer.
A sinusoidal current is zero and increasing at t = -3.33ms; the next zero crossing occurs at t = 6.67ms. a) calculate T, F, and W. b) if i(0) = 25.98 A, Find i(t). c) By what angle does i(t) lead another current i(t) = 5 sin (wt - 5°) A.
Why radio waves is chosen for remote/close range Transmission ? and How to Construct a simple radio receiver ?
A 400-kV transmission line has a hot-weather power rating of1400 MVA. If the transmission line is operating in cold weather, itis rated for 2200 MVA (at 400 kV). The transmission line is undercold weather conditions, and the operating voltage is 3..

Design a counter with TFFs that goes through the following binary sequence: 0, 2, 5, 3, 6, 4. And Design another counter thatgoes through 0, 5, 4, 6, 3, 4.
Contains basic function in MATLAB files. Write MATLAB script(s) to plot the basic signals below in two subplots. The upper subplot should be a continuous waveform (don't do g) and the lower subplot should be a discrete plot.
1. What is the force on a 10 cm wire carrying 1.0 A in a uniform magnetic field of 500 gauss 2. In the above example, if the current is in a loop of width 6.0 cm and the coil lies in the plane of magnetic flux, what is the torque on the loop
The load on a 460-V, 60-Hz, Y-connected, balance three-phase source consists of three equal Y-connected impedances of 100+j100 ohms, and three equal Delta-connected impedances of 300-j300 ohms. Compute the line current, power, and power factor for..
