How can these passive RLC circuits change a sinusoid's frequency?
Given a sinusoid input of frequency f, an RLC network, no matter how complex, should produce a sinusoidal output of frequency f, with possible attenuation and phase shift. At least that's my ...

What signal to use for identifying control-to-output TF of resonant converter? Is it required to have a transfer function when PI tuner is present?
I have a resonant converter (DC-AC) built on Simulink and I want to find out its control to output (current) transfer function using the system Identification toolbox in MATLAB/Simulink. I have three ...

Maximum Power Transfer Theorem Question
I'm missing something here. The maximum power transfer theorem states that max power transfer from source to load happens when source impedance matches load impedance.
In the case of a 10V source ...

Finding Deboo's integrator time constant and transfer function
I tried to determine the transfer function and time constant of Deboo's non-inverting integrator. If I calculate with an ideal op-amp, then my calculation fails if the ratio of R2/R1 and R4/R3 is the ...

In this transfer function equation, is "20" inside the log() the value that was factored out?
In the given problem, we're supposed to find the gain of the transfer function. The solution provides an equation to the problem. The question I have is, for that particular equation, is the value ...

Is it possible to simulate reflections by designing an RLC transfer function?
Assume that you're knowing the PCB stack and the geometry of the conductor.
You're computing the capacitance per mm and inductance per mm and also the total resistance of the conductor.
That means you ...

Why is inverse of a transfer function not really a correct way to think while doing circuit analysis?
When we try to predict the circuit behaviour using transfer function, everything works fine in forward direction (Vin to Vout).
But if we try to predict the circuit behaviour in reverse direction (...
