a)Constract the use of electromechanical relays against a PLC in the implementation of an automatic solution, giving the merits of using the PLC.
b) Two digital outputs y and z need to controlled as follows:
Y turns on if inputs x1 and x2 are high or if input x3 is low and input x4 is high. Y stays on for 7s and then turns off, while simultaneously setting the output z to high. Z stays high for 5s, following which the sequence is repeated. The process is started by pressing a start pushbutton and is stopped by pressing a stop pushbutton.
Draw a ladder logic diagram to program a PLC for this application.

Recall that a float is stored in the following format:

±sign 1.mantissa • 2^exponent?127

where sign is 1 bit, exponent is 8 bits, and mantissa is 23 bits. Write a C function that accepts an int parameter and returns a float represented by the bits in the int. The 32-bit integer is organized as 1-bit sign, 8-bit exponent, 23-bit mantissa. For example, 0x3F800000 represents 1.0 because the sign bit is 0, the exponent is 127, and the mantissa is all 0’s.

It has to be a proper c executable code.Please help.

Three balanced 3-phase loads are connected in parallel. Load 1 is Y-connected with an impedance of 400 + j300 ? per phase, load 2 is ?-connected with an impedance of 2400 – j1800 ? per phase, and load 3 is absorbing 172.8 + j2203.2 kVA. The loads are fed from a set of distribution lines with an impedance of 2 + j16 ? per line. The magnitude of the line-to-neutral voltage at the load end of the line is 24?3 kV(rms). Find the total complex power delivered by the generator

Using design theory:

construct a difference aplifier that meets the following design equation: V0=2Vb-4Va. You must use resistor values that range from 200 Ohms - 50k Ohms. The rail voltage must be +- 12V.

Use your design equations to determine the output voltage Vo for the following input cases:

1. Va= 1.0V DC, Vb= 2V DC

2. Va=Vb=1.0 Vpp 1 kHz sinusoidal voltage

3.Va=Vb=3.0 Vpp 1kHz triangular waveform voltage
