Design a single stage BJT amplifier with the following constraints:

This involves the following:

-DC and AC analysis and the frequency response of the amplifier.

-Use a 2N2222 transistor

-Power supply (VCC): 6 V

-An input impedance near to 3 kΩ

-Overall midband voltage gain of -30 V/V

-A load resistance of 2 kΩ

-The input signal has an RSignal of 500 Ω

-Choose a good Qpoint and select the coupling and bypass capacitors to obtain an fL-3dB of 100 Hz.

-The capacitors and resistors should have commercial values

-Part of the design requirement is that the amplifier will exhibit maximum symetrica1 swing in the voltage collector.

The Total Harmonic Distortion of the output voltage should be less than 5% when a sine wave with an amplitude of 5 mV is applied by the signal.

Determine the analytical fH-3dB of the final design of the amplifier. When the final design is completed, obtain the frequency response of the amplifier to verify the midband voltage gain, fL-3dB and fH-3dB.

It is planned to recruit trainees for the summer period in CERN Laboratory in Switzerland. If you are an engineering student and is asked to prepare a project proposal which explains the work to be done. It should not exceed two pages. Make sure that there are budget items in your project application. The upper limit of the project budget is 25000 Euros. your proposal should stand out from other applicants. you can also add the sections that you consider important.

What is meant by race-condition on ripple counter?

Battery capacity is sometimes given in units of Amp-Hr. If a 9 volt battery has a capacity of 500 milliAmps-hr's, how long would it take for each resistive circuit to discharge the whole 9V battery? Hint: 500 mAmps-hr essentially means it can maintain a 500 mAmp discharge from 1 hour only.

Compare refined gasoline and diesel in terms of “kW-hr/ liter” units to Li ion battery technology

The higher the wind speed, the quicker a body cools. To quantify this wind speed chilling effect, both the U.S. and Canadian weather services have determined wind chill temperatures for temperatures below 50°F and wind speeds above 4 mph in the United States and temperatures below 10°C and wind speeds above 4.8 km/hr in Canada. An approximation of the official wind chill temperature, for both metric and English units, is given by this formula:

WCI = K1 + 0.6125 Ta - K2Ws0.16 + K3TaWs0.16
The following chart lists the correct dimensions and values for both systems of units:

Using the wind chill formula, write, compile, and run a C++ program that displays a table of wind chill indexes for temperatures from 2°C to 10°C, in 4-degree increments, and for each temperature, wind speeds from 5 km/hr to 11 km/hr in 2-km/hr increments.

Draw the logic diagram for the function f=ΣA,B,C (2, 6, 7) using only AND, OR, and NOT gates.

Then draw logic schematic with only NAND gates, and appropriate resistors/LEDs to have LEDs to show the inputs and the outputs. You will need to swap out your AND, OR, and NOT gates as appropriate. You must show all gates, do not apply the involution theorem in the process. This means you will have more NAND gates than possible to implement with your equipment in this drawing. You will then make note (label) which NAND gates can cancel due to the involution theorem, this will allow you to make sure your circuit can be implemented with your equipment. You do not need to redraw your schematic after you document when you are applying the involution theorem
