Design a circuit that provides a voltage gain of + 3. Draw the circuit schematic identifying supply voltages and show your work on component selection.
Suppose a car of mass m moving on a straight west-east highway at velocity v(t) (positive for motion from west to east) experiences aerodynamic drag force with magnitude v(t) opposing its motion.
a) Write the system of linear equations in the form of Ax = b: (b) Use Guass-Jordan method to find A inverse (c) Use A inverse to solve the system of equations. -2x1 + x2 +x3 = -12 4x1 + 2x2 + 4x3 = 7 -x1 + x2 + 2x3 = -3
Design a low pass filter with a single op amp, maximum gain of 40 dB, and a corner frequency of 60 Hz. Assume that the input signal has a maximum source resistance of 100 W and you want the error in the gain the pass band
Consider an AlGaAs based heterostructure laser diode which has an optical cavity of length 200 microns. The peak radiation is at 870 nm and the refractive index of GaAs is about 3.7. What is the mode integer m of the peak radiation
A field technician measures the signal level at the output of a cable amplifier as 42.5 dBm, and measures the input to the same amplifier as 24.8 dBm. What is the gain of the amplifier
What is correct symbol rate (pulse rate) for this link? What is the bit rate with BPSK modulation? What is the bit rate with QPSK modulation?
A signals values have a range of +- 5V and you wish to make measurements with an analog quantization size no mate thatn 5mV. What minimum resolution A/D converter is required to perform this risk
a) the synchronous generator has a unique ability whihc places it at the top of the heap of all machines that might be used for generation of electric power. This unique capability is what allows the business of electric dispatch to even occur.
An electric bass amp is advertised as being able to deliver 200 Watts toan 8 Ohm speaker and 300 Watts to an 4 Ohm speaker. If the amp is a voltage source with an internal resistance, what is the value of the internal resistance
A 35-year old female worker receives an x-ray exposure of 5.2 rad (whole-body) while carrying out emergency procedures in a nuclear accident. Discuss the health risks assumed by this worker as a result of the radiation exposure.
Let x(t) and y(t) be two real, periodic signals that are orthogonal to each other. Show that the power of the sum of the signals (i.e., x(t) + y(t)) is equal to the sum of the individual powers (i.e., Px + Py).
Then find the total energy stored in the battery before it is connected to the bulb. Determine the total amount of charge that has pessed through the wires that connect the battery and the bulb.
