01Series path
Put R, L, and C in the signal path.
02Load
Show where the filtered output is taken.
03Damping
The resistor sets bandwidth with the other values.
Use for a simple series-tuned bandpass example.

שאלות נפוצות
Why is a series RLC circuit bandpass?
Its impedance is lowest near resonance, so more signal current reaches the load at that frequency.
What sets its bandwidth?
Resistance relative to inductance and capacitance determines damping and therefore bandwidth.
Where is the output measured?
This example takes output across the load resistor after the series-tuned path.
