I'm learning more frequency domain analysis and LTspice tools, and I made this circuit and so far found some (jw) eq to get the correct branch currents.
But what foes it mean, for the current through the 1k resistor (green trace) to level off to -60dB , what does the -60dB mean, I can see the voltage at the node between 22n and 1k approaches the full 20V, and so it's amplitude in the bode plot (blue trace) , approaches 0dB. So why doesn't the current magnitude approach the branch current ratio of 2k||1k of 1:2, 10mA:20mA, so 2/3 of total, what's -60dB mean ?
the cursor box disappeared when taking the snap, so that's NYC wall paper in the pic too
Also in transient mode, how to I easily measure the phase and time between 2 traces ?
