3. Use matlab to plot the output voltage of an inverting operational amplifier given the following conditions: K = Gain of the amplifier = 12.5. Vi = input voltage -2.5 < Vi < 2.5 V], (use 0.25 increments). V+ = positive power supply voltage, V+ = +20 V. V- = negative power supply voltage V- = -20V. Vo = output voltage Vo = -KVi Recall that if the output voltage Vo is greater than V+, or less than V-, the output voltage Vo gets clipped to the V+, or V- voltage, (clipped at the rail voltage).

I have a project where i have to include solar cells and piezoelectric transducers in an umbrella.

They will be used to transform solar energy and energy from rain respectively into electrical energy. (stored in a lithium battery)

I would like to know how i should build up the circuit. As in:

1. should i connect the solar cells in series?

2. How do i connect the piezoelectric transducers? what type of rectifying diode i need for this experiement.

3. What calculations i can use to show that the energy harvested by the piezoelectric transducers will be very little?

4. What calculations i can then use to show that to have more energy i make use of solar cells?

Write code using the Arduino IDE that compiles with no errors.

2-bit adder: The code must read two digital input signals and turn on two LEDS as needed to show the sum of the inputs. e.g. 0 + 1 = 01.

Design a circuit and write a verilog code description of the 16-bit right rotator using barrel shift method

please Use Matlab to plot simulated results and to plot and conduct the mathematical analysis of the data below:

note: I only need these things

1- simulate the RC filter in the frequency domain in order to obtain magnitude and phase response plots.

2-obtain the transient response plots of the capacitor voltage and the current as functions of time.

1. Explain impact ionization and zener/tunneling breakdown. Which one is likely to cause breakdown in following:

a. GaN Schottky barrier diode with barrier height 1ev.

b. Heavily doped P+/N+ GaAs diode.

c. Heavily doped P+/lightly doped N-Si diode.

Define a 3 phase short circuit and a line to ground faults in a PV system. How it affect the load and how it can be eliminated. Also make analysis on how it affect active and reactive power and the efficiency of the system.

Assume you have a WAV file containing an audio with noise. The audio was sampled with a sampling frequency of 8ksamples/second. If you play the audio file, you will be able to notice that there is a small tune along with a strong noise. Design a digital filter using Matlab or Octave to remove the noise. Write the code showing all steps of designing a digital filter? Need help please

b) The load connected to a three-phase supply comprises three similar coils connected in star. If the phase currents are 10A and the total active power and power factor absorb by the loads are 3kW and 0.8 lagging, respectively. Find:
i. The magnitude of phase and line voltages
