An LCD 16x2 display is used for PIC16F1619, if Port C is connected to 8 data pins of the LCD. Pin4 and 5 of port A are connected to EN and RS respectively. RW is tied to the ground. Write a C code to set up 2 lines, 5x8 matrix, 8-bit mode and force the cursor to the beginning of the first line.

The force exerted by an electric charge at the origin on a charged particle at a point (x, y, z) with position vector r = <x, y, z> is F(r) = Kr/|r|³ where K is a constant. Find the work done as the particle moves along a straight line from (3, 0, 0) to (3, 4, 5).

What is the relation between the two outputs of 74ls151?Is ENABLE input active-HIGH or active-LOW? a) Identify the ENABLE pins for 74ls138 chip. Are these pins active-HIGH or active-LOW? Are the outputs of 74ls138 active-HIGH or active-LOW? c) When used as an octal decoder, this IC converts what type of input code into a corresponding activated output? d) When used as a DEMUX, which input(s) may be used as a data line and be distributed to the output?

A load supplied by a 3-wire d.c. distribution system takes a current of 600 A on the +ve side and 480 A on the −ve side. The resistance of the outer conductor is 0·015 Ω and that of the middle wire is 0·03 Ω. Determine the voltage at the load end between each outer and middle wire. Supply voltage is 500/250 V

Design a 5 bit binary counter on logicly?

Please discuss the definition and theory on Power amplifier and phase lock loop with diagrams

Transformer and Auto Transformer

Q1: What do I need to know to solve Ideal Transformer, Transformer, and autotransformer problems?

Q2: What does it mean referred to primary or secondary side?

Q3: How to draw phasor diagram ?

Q3/ Draw the out voltage and current waveforms of a single-phase cycloconverter connected to a purely resistive load. The following information could be useful: Load Supply Voltage, Supply Frequency Output Frequency Firing Angle At 202 230Vrms, 50 Hz 12.5 1300 sec Your drawing should contain all the detaiks including Amplitudes, Time, Degrees and Axis Names,

For a signal x(n)=sin(2*pi*n/5) defined for n=0to7, evaluate the Fast Fourier Transform using signal flow graph. (Use decimation in Time Algorithm).                                               

From 1+K*L(s)=0

L(s) = 1/((s+1)(s+2)(s+10))

Solve for gain K where the root locus passes through the damping ratio. z=0.176. With out Matlab. Please show all work.

Note: I know we need to use some trig and the magnitude criteria but u cannot seem to figure it out. Thank you!

True and False

1. The instruction register stores machine code for the instruction being executed.

2. Before a digital computer may execute an instruction, the instruction code must be fetched from memory.

3. A pointer is a binary code for data in the arithmetic logic unit.

4. Von Neumann computer architecture stores data and instruction codes in the same memory.

5. Complex instruction set computers have instructions with greater speed than those in reduced instruction set computers.

Indicate what considerations should be taken into account for a good design of an audio amplifier.

Sketch and label a clamping circuit. Use a 2.5 V rms source and an ideal diode. Explain how it works. Show the voltage wave forms in a diagram, giving numeric values where appropriate.
