How to use wolfram alpha to plot frequency response

AI Thread Summary
To plot the magnitude and phase response of the transfer function H(s) on Wolfram Alpha, users can utilize the functions abs(...) and phase(...) with the imaginary unit i. For phase plotting in degrees, the 'bode(...)' function is recommended, which also provides additional plots like Nyquist and Nichols. Users expressed appreciation for the guidance, noting its practical application. There is a learning curve for understanding concepts like Nyquist and Nichols, but the tools provided are seen as beneficial. Overall, the discussion highlights effective methods for frequency response analysis without Matlab.

Can someone please tell me how I can plot the magnitude and phase response of this transfer function on wolfram alpha as I don't have Matlab:

H(s) = -(2.1953*10^12)/(66600*((j*ω)^2)+808823539.4*(j*ω)+2.1626*10^12)

A link to the output would be very useful also, thanks heaps.

You can use abs(...) and phase(...) with i as the imaginary unit.

thanks bro, your post has improved my life quality by a factor of 0.0001, one more question: How do I make it plot the phase in degrees instead of radians.
 
You can also use 'bode (...)', which will plot the amplitude and phase in degrees. As a bonus you get Nyquist and Nichols too :)

haha wow that's really cool, its going to be very useful, i got to admit i have no idea what the Nyquist and Nichols are atm but ill get there eventually. thanks for the help.
 
Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
