Its an electrical circuit problem. I have obtained the Transfer function. I have substituted in the inductance/capacitance and resistance values and am now stuck on this part of the question:

d) Find |H(ω)|, the modulus of H(ω), and determine its asymptotical values for ω = 0 and ω → ∞. Sketch the form of |H(ω)| and describe the behaviour of this circuit.

2. Relevant equations

Found the he modulus of H(ω) to be:

[tex]\frac{sqrt{(1*10^{-11}\omega^2)^{2} + (5*10^{-6}\omega)^{2}}{\sqrt{(1*10^{-22}\omega^{4}-1.225*10^{-10}\omega^{2}+1)^{2}+(1*10^{-16}\omega^{3}+6*10^{-6}\omega)^{2}}}[/tex]

3. The attempt at a solution

if ω = 0 then modulus |H(ω)| =0

as ω → ∞ i don't know what to do.

do i divide everything inside the square root by ω^4

in that case as ω → ∞, |H(ω)| also is 0. Is this correct?
