I already mentioned in several posts my simulator NL5, which would be a good tool to be used instead of (or along with) what you call "hand calculations".
The idea of this simulator is that it is using very simple "generic" models: ideal diodes and transistors, OpAmps, switches, R,L,C, V and I...
Not exactly. Here is what you'll see if you model lossless line with LCs: a lot of oscillations, quite different from ideal line response. The better way to model such a line is to consider V and I inside the line as a combination of two waves: forward and reflected. I think you can find...
how to calculate phase between two signals
Please note that RC-CR solution works only at fixed frequency f=1/(2*pi*R*C). If frequency changes, the amplitudes and phase shift also change.
Integrator always has 90 degrees phase shift, but the amplitude will change as well.
ACiDUser, are you sure you are not mixing phase and frequency modulation. Since phase is integral of frequency, you can easily get what you see on the graph.
Re: What is importance of frequency domain analysis over ti
This must be not a simplest explanation, but anyway...
Every system has a transfer function in frequency domain: T(ω). Very often it is done not as a function of frequency ω (ω=2πf), but Laplace parameter s=jω: T(s).
If you apply...
In the analog system, information is usually not discrete, it is continuous. For instance, if the signal is coded by the amplitude of the signal, and you've measured very small (1 nV) change of the amplitude, you consider this change as an information. Then any noise, which always exists in the...
I think, because if you know frequency response of the system, you can easily predict its response in time domain for any type of input signal. (And vice-versa as well). Another reason could be well known technique of determining system stability based on frequency response.
For switching capacitors circuit you can try NL5 simulator. It was designed for SMPS, with any sort of switching circuits in mind. Here is screenshot of simple schematic.
Thanks,
Alexei.
adc input signal bandwidth
This is probably related to Nyquist theorem. Simply speaking, if ADC samples data with frequency f, the input signal spectrum should be limioted by f/2, otherwise the aliasing may occur.
An example: if sampling rate is 1 MHz, and input signal is 1 MHz sinewave, the...
equivalent circuit of inductor
Inductor is always inductor, whatever signal amplitude is (as well as capacitor is always capacitor). As for frequency, inductor is short at low f and open at high f, and capacitor is vice versa.
