3. Design and draw a circuit using the cascade system to operate
two cylinders (A and B) which, on the operation of a start valve,
produces the sequence A – B + B – A+. The cylinders should park in
the positions B – A + when the start switch is in the ‘off’
position.
4. Modify the circuit designed for question 3 to provide an
emergency stop which will park both cylinders in the extended
position (i.e. A +...

Draw the resting circuit and explain each part and what it represents. Show the calculation (Nernst equation) of the equilibrium potentials (with reference for the concentrations), give a reference for the resting potential, and apply physics to show how the chosen resistances are able to yield the resting potential.
1. Draw a simple circuit diagram of half wave specific with
sinusoidal input signal define on V_in (t) = A*cos(wt^2*pi*f) with
peak voltage of 10 V and frequency of 60 Hz.
2. Design the output voltage in terms of fourier transform.
3. Use matlab to plot the frequency spectrum of the rectified
signal for magnitude and phase use load resistance as 1 kilo-ohm
and cutoff frequency as 10 Hz.
4. Design a second order butterworth filter of a specific cosine...

your answer with a simple numerical example. What benefits could a
firm obtain from using interest rate swaps? (150 words)
(b) Why must the price of an American call option on a stock
that pays no dividends always be higher than its intrinsic value?
How can the price of an American call option be determined from the
price of a European call option on the same stock with the...
