    How to prove that the L2 norm is a non-increasing function of time?

    Thanks! I have done what you said (note that I just made a change in variables so I stick to the symbol convention of integration by parts.): \\2\int_{0}^{L}\frac{\partial^2 s}{\partial x^2}s dx \\ \\ \\u=s, dv=\frac{\partial^2 s}{\partial x^2}dx \\du=\frac{\partial s}{\partial...

    How to prove that the L2 norm is a non-increasing function of time?

    Homework Statement Homework Equations How can I start the proof? Shall I use the Poincare inequality? The Attempt at a Solution Well, I know that this norm is defined by , but still I don't know how to start constructing the proof?

    Engineering Thevenin equivalent of resistor only circuit

    I see your point. However, that is pretty common. Think of it as a circuit with 0 V (independent) source.

    Can overdrive voltage never be less than zero?

    You are right in that Vov=Vgs-Vt In your case, Vov would be negative. What does that mean? Well, there are two cases to consider in general when Vov < 0 (although it is obvious that the transistor is NMOS since Vt > 0; unless, of course, it was given that |Vt|=1, then it is a PMOS and your...

    What are the best books for designing RC and LC oscillators with op-amps?

    I would recommend Microelectronic Circuits 5th (or 6th) edition by Sedra/Smith. Well, it is not too detailed, but it gives the whole picture with a lot of good insights regarding signal generators and waveform-shaping circuits.

    Finding h parameters when capacitors and inductors involved with resistors

    Well, first write the h-parameters equations: V1 = h11*I1 + h12*V2 I2 = h12*I1 + h22*V2 And to find the parameters follow the formal procedure: First, by shorting V2 (that is, making V2 = 0), you can find: h11 = V1/I1 h12 = I2/I1 Then, by opening the first port (that is, making...

    Reversible Carnot Cycle and Heat Engine

    For part a): Use this equation to calculate the heat lost from the water (the heat input to the plant): Q(rate) = m(rate of mass flow) * specific heat * temperature change for b): Since the plant is assumed to be reversible, use the equation: Qh(rate)/QL(rate) = Th/TL for c): The maximum...

    Engineering Thevenin equivalent circuit help

    2 or 3 voltages, it doesn't matter. It is the same approach most of the time :smile: Find the voltage across AB, that is: Vab (using nodal analysis). Then find the short-circuit current Isc, that is in the direction of the voltage DROP across AB (using mesh current method). Then it is a matter...
