    Finite state machine (summarizing)

    Hello, I have an FSM which has 1 serial input and 4 outputs. The FSM must react to the table attaced in file. I can see that if the input is(for example)4 the output is 7(+3). I have to draw a state diagram(mealy). I can't solve it. Need some help Thanks

    Exceptation of energy by Hamiltonian

    Hello, The question says that we can write the Hamiltonian of the harmonic oscilator like this: H=0.5*[P^2/m + (4*h^2*x^2)/(m*σ^4)] where h is h-bar I need to calculate the expectation value of energy of the oscilator with the next function: ψ(x)=A*exp{-[(x-bi)^2]/σ^2}. I tried to the...

    Maximum difference of voltage in converter

    hey, this is the trouble : look at this part. [(Vin/10)*2^n]^2 lets take Vin=6.3Volt --> [2580.48]^2=2580^2=6656400/ and now: this is what you suggest: [(Vin^2)*(2^2n)/100] --> [6658877.03]=6658877 what we get is that: 6656400 not equals 6658877 )-: thats what I am trying to explain that i can't...

    Maximum difference of voltage in converter

    sorry but can't understand how do you take the ^2 and make it inside the integer in brackets. and what is w/r/t?

    Maximum difference of voltage in converter

    it can't be cleaned up because the part in brackets [ ] is integer. i can't take out of that nothing for example: vin=6.3 and n=12 →vout=3.9675volt there is know way to clean it up

    Maximum difference of voltage in converter

    hello I got the Vout but look at it: I have an answer with a part which is taken only after calculation as a number without partions so there is no way to do some algebra on: vin-vout. But: The question was how to find what will be the maximum difference and this is the problem

    Maximum difference of voltage in converter

    I have a successive approximation ADC converter (left) and is connected to a DAC converter. The Vref of the ADC is 10V and the Vref of the DAC is brought fom an internal leg of the SAR. This internal leg is the output of the SAR's internal DAC. The question is: what can be the maximum...

    Average power of a signal in spectral display

    Hello, I've got a modulated signal - Y(f) (the question doesn't say if AM or DSB or whatever) which it's spectral modulted signal is shown(in the file I've uploaded).its is modulated by a carrier of sum of several COS. It asks what is the average energy or power( I should decide) of the...

    How Does Input Resistance Affect Op Amp Performance?

    the resistance named Rin is 400K. But: the input resistance of the circuit is not 400. that's what I have to find

    How Does Input Resistance Affect Op Amp Performance?

    I have an un ideal OA aplifier(Amax=-9.975). I have to evaluate its Rinput--> it has to be something like 10*10^10 Ω I need to put a potenciometr after Vin and to "play" with it when I get half of Vout/vin. when do I need to put it? and what is my voltage equations? thanks.

    How Do Antenna Size and Frequency Affect Power Density Calculations?

    Antenna is in size of 0.5[m] X 0.5[m], with transmit frequency of 10GHz. In a distance of 100m the electric field is 250 [V/m]. I calculated the density of power with the formula: 0.5*(E^2)/(120*pi) and got: 82.891 [W/m^2]. the question is: can I calculate the density of power again but un...

    Double Interpolation thermodynamics

    For Refrigerant 134a at T = 60C and v = 0.072 m3/kg, determine pressure in kPa. the v is in superheated region so I have a mini table look like in the picture I've added there I need to do a double interpolation but don't know how. the anser for p is: 3.63Kpa. Thanks

    The emf of a string in a circle - magnetic fields

    Alright now I understand it: the emf of the triangle is the emf of the rod only becaude the Electric field on the radius is perpendicular to it and so E*dl = 0. And in the second question the E*dl on the wires and the resistor is not 0 so I get another EMF across the loop!
