delayline

Hi everyone! I intend to delay a 1Vpp mostly sinusoidal signal in the 100Hz range for 5µs. My first inuition was a 1000m wire, but I decided to go with cascaded LC-filters first, as in this. \( t_{d}=\sqrt{L*C} \)=0,07µs per stage with 100nH/50nF, so I straightforwardly LTspice-simulated a...
