Obtain the STDP(.Spike-timing-dependent plasticity feature) by applying it to any STDP circuit in the LT spice program.

please I need that in less than 5 hours.
I have an exam.

(c) What fraction of the voltage is reflected?

(d) What fraction of the current is reflected?

(e) What fraction of the power is reflected?

Write a MATLAB code to obtain the following. Keep your code commented whenever required. Copy your source code and command widow outcomes and screen shots of any plots in your solution.

Generate the following vectors and also implement the Table-1 operations-map by employing the switch statement and an appropriate loop.

• Generate a vector ‘DEC1’ as follow.

• Concatenate vector ‘DEC1’ eight times in order to obtain a bigger row vector ‘DEC’

• N = The length of vector ‘DEC’
• Generate a vector ‘t’ with ‘N’ equally spaced values within the range of 0 to 1
• x = round of 26sin(2π9t).
• y = ‘x’ multiply by 2.

* In Table-1, ind is presenting the vector index.

a) Describe how each of the following can be achieved
i. Controlling a DC motor with pulse width modulator.
ii. Controlling a stepper motor that has a built-in controller.

Design an analog-digital converter circuit with OpAmp that receives a 5 Vp sinusoidal signal and a 3.5 V trip level as input. It must deliver a TTL (Low / High) signal as output.

In a differential amplifier, the non-inverting input is 3 cos (600t + 45◦) mV and the inverting input is 4cos (600t - 45◦) mV. The output is vo = 3cos (600t + 45◦) + 4.004cos (600t - 45◦) V. The CMRR is of ____ dB

Design a system which can add two 2-digit binary numbers (no carry in). Use a truth table approach and use karnaugh-map

Write a Boolean equation for each output and draw circuit.

Explain earthing in DC traction applications with a simple diagram. What are the hazards involved? Explain the mitigation strategies with reference to the standards

1. Explain following instructions with an example
   1. Goto

2. RRF

3. SWAPF

4. XORLW

A point charge q = 40 nC has a velocity 3* 106 m/s in the direction av = 0.2 ax + 0.75 ay – 0.3 az. Calculate;
a) The magnitude of the force on the charge due to the field B = 3ax + - 4ay + 6az mT.
b) The magnitude of the force on the charge due to the field E = -2ax + 4ay + 5az kV/m
c) The Lorentz force due to the two fields in (i) and (ii) above.

Hints: In order to display all the combinations of input, you should use “Force” or “Clock” to cover all the combinations of the inputs. For example, for input A, B, C, the waveforms below cover all combinations. (Similar to all the combinations in a truth table.)

In your submission, please also show your VHDL program (in text or screen capture). You may also show the transcript in the screen to confirm the compilation of the program is successful:

1. Write down VHDL program for half-Adder. Use modelsim or other software to compile, simulate and print out the waveforms/time diagram to cover all the combinations of the input.

Explain circular convolution and DFT? provide an example.
