A pressure transducer provides an output voltage (Vo) given by the expression 𝑉𝑜 = (200 + 0.2 𝑃) mV, where P is the pressure to be measured, in mmHg. If P varies between 100 and 350 mmHg, design a circuit which will provide an output linear with P, with a sensitivity of 100 mV/mmHg. You are provided with ideal components and a power supply of 10 V.

10 Hp, 220 V shunt DC motor takes a line current of 4 A when running light. Calculate the efficiencies as a DC motor when delivering i) half load and ii) full load output, if the armature resistance are 0.45 Ω and 220 Ω, respectively.

Design an ideal differentiator with frequency response H(e^jw)=jw; |w| <=π. Use hanning window with N=9.(don't use MATLAB code)

Design an ideal Hilbert transform with frequency response H(e^jw)=-j for 0<=w<=π and j for -π<w<0. Use hamming window for N=7. (Don't use MATLAB code)

A balanced Δ (delta) connected source has an internal impedance of 0.018+j0.162 Ω/phase. At no load, the terminal voltage of the source has magnitude of 380 VLL. The source is connected to a Δ (delta) connected load, having an impedance of 7.92+j6.35 Ω/phase through a distribution line having an impedance of 0.074+j0.296 Ω/phase. a) Draw the single phase equivalent circuit of 3-phase system b) Calculate the three line currents c) Calculate the phase currents of the source d) Calculate the magnitude of the line voltage at the terminals of the source

A single-phase asymmetrical semi-converter feeds an R-L load with R=50 Ω and a large L= 10 mH so that load current is constant. The source voltage is 230 V, 50 Hz. For a firing angle of 600, determine: (i) Average value of output voltage and output current. (ii) Average and rms values of diode, thyristor and source currents.(iii) Input power factor. 

Design the buck and buck-boost converters for following specifications: Vin = 24 V, Switching frequency = 25 kHz, Vo = 10 V, Po= 48 W. Inductor current ripple is 10 % of load current and capacitor voltage ripple is 1% of output voltage. Assume necessary data if required.

 The work required to compress a gas reversibly according to PV1.3 =C is 68KJ. if there is no flow  determine the change in internal energy, enthalpy and heat if the gas is CO2

This task requires you to write a report on the growing development in networking technologies. Your report should include important features such as: memory capacity, wireless implications, smart sensors, control software etc.

Your report should show evidence of independence research. You should also include a bibliography.

The modern PLC uses a wide range of networks to control devices. 

Using research, you are to compare the key differences between Profibus and Profinet networks highlighting key differences. 

Your report should include important criteria such as standards and protocols.
