how to calculate image frequency in fm
The IF frequency for FM is 10.7 MHz. Therefore, the image is 21.4 MHz away from the station. Therefore, for FM radio, which only has a range of 88 MHz - 108 MHz (20 MHz), the image is not within the FM receiver tuning range. So, you can't get an image...
lissajous method formula
It is actually the arcsin of the ratio of the vertical and horizontal displacements. The derivation is straightforward. The Lissajous curve is ploting the first waveform (x=V1sin wt) versus the second waveform (y=V2sin wt + phi). So the steps would be to get an...
Re: Delta sigma modulator
The principle of a sigma delta modulator is take an initial comparison of the signal with a reference, measure the analog error, integrate and adjust the error. There is a nice little applet that shows exactly how this is done...
Re: SOI
What kind of analysis?
You want analysis of advantages of soi substrate? or the spice models of devices built on soi? In either case, it would be heavily dependent on the particular fabrication process used to make the soi substrate.
You don't always use the correction components in parallel. For example, to remove the effect of leakage inductance, you would of course use a capacitor bank in series.
