Is the fundamental frequency considered an odd harmonic? Thanks for any clarification

Thanks MATLABdude, so am I right to say that for non periodic information signal, FM modulated signal is non periodic, just that it is not very noticeable?

From what I observed, if the information signal is periodic, the modulated signal from FM and AM will be periodic. However, if the information signal is non periodic, the modulated signal will be non periodic for AM. Please correct me if I am wrong so far. However, I am abit unsure as to...

For frequency modulation, will the modulated signal always be periodic? or does the periodicity depend on the modulation index? or does it depend on whether the message signal is periodic? Thanks for any help on this

Will we get a high frequency signal from convolving 2 high frequency signals? Also will we get a low frequency signal from convolving 2 low frequency signals? How about convolving one low and one high frequency signal? My intuition tells me its low frequency signal. Thanks for any...

Can I clarify that the reason such a filter cannot be constructed is because sinc function extends to infinity and not because the impulse response is non zero for negative time? Is it possible to construct a filter which is non zero for negative time? Thanks in advance

Hey guys, I have some problem understanding why an ideal low pass filter cannot be implemented in reality. I do not understand the reason given in wiki " because the sinc function's support region extends to all past and future times. The filter would therefore need to have infinite delay, or...

Thanks everyone for the input!

I was wondering what's the main advantage of choosing one over the other, besides common drain having to suffer body effect. How do we determine if a CC is better or a CD is better to use as a buffer?

Thanks for the clarification. I get it now.

But doesn't the weight of the steak constitue a net external force even at the instant of collision?

Homework Statement A spring of negligible mass and force constant k = 400 N/m is hung vertically, and a 0.200-kg pan is suspended from its lower end. A butcher drops a 2.2-kg steak onto the pan from a height of 0.40 m. The steak makes a totally inelastic collision with the pan and...

I was wondering why the current waveform in a rectifier circuit that uses transformers, is not out of phase with the voltage waveform. Does the transformer not shift the current waveform out of phase with the voltage waveform? Thanks for any help.

Homework Statement A 5.00-kg ball is dropped from a height of 12.0 m above one end of a uniform bar that pivots at its center. The bar has mass 8.00 kg and is 4.00 m in length. At the other end of the bar sits another 5.00-kg ball, unattached to the bar. The dropped ball sticks to the...
