The request
“Draw a five-band microphone-preamp equalizer with a 100 mV AC input, five LC filter branches with the shown values, and 10 kΩ input and output resistors.”
Then tryRemove the highest-frequency filter branch.Change the output resistor to 22 kΩ.
What is in this drawing
Read the decisions behind it.
01
Modeled the preamp output as an AC source with 10k input load for stable reference.
02
Used five parallel series-LC branches to create tunable bandpass responses between input and output.
03
Tied every resonant branch to a common ground and output load for clean netlist render.
Reuse this layout when producing a small passive EQ or tone-shaping stage in audio effect or microphone interface projects.
