    Doubts Modulation
AI Thread Summary
The discussion revolves around the correctness of the spectra for DSB-SC and SSB modulation. Participants confirm that the provided spectra appear accurate, particularly for SSB and DSB-SC. There is some uncertainty regarding VSB, but reference materials from Stanford are suggested to clarify this. One participant notes that the DSB spectrum may actually represent DSB-SC due to the absence of a visible carrier peak. Overall, the insights provided aim to validate the understanding of the modulation types discussed.

The SSB and DSB-SC spectra look correct to me. I wasn't too familiar with VSB, but a quick google led to these lecture notes from Stanford (here). There is an image (shown below) in the notes which supports your understanding of VSB, so I think you are correct.

(I think the DSB may be DSB-SC as I cannot clearly see the carrier peak shown)

Hope that is of some help

Thread 'Have I solved this structural engineering equation correctly?'

Hi all, I have a structural engineering book from 1979. I am trying to follow it as best as I can. I have come to a formula that calculates the rotations in radians at the rigid joint that requires an iterative procedure. This equation comes in the form of: $$ x_i = \frac {Q_ih_i + Q_{i+1}h_{i+1}}{4K} + \frac {C}{K}x_{i-1} + \frac {C}{K}x_{i+1} $$ Where: ## Q ## is the horizontal storey shear ## h ## is the storey height ## K = (6G_i + C_i + C_{i+1}) ## ## G = \frac {I_g}{h} ## ## C...
