Hello,I have a component YIG oscilator shown bellow in the link.
A schematics is presented bellow.
As describled in the manual we created a magnetic field on the coil (L1).
For creating magnetic field we need AC current however our input is DC voltage(in the schematics input 0-10V DC).
How its possible?
Also OPAMP virtual ground amplification works on AC (DC is just for bias) so again we need AC as input .
Also at pure DC input our coil is short circuit and capacitors are open circuit.
How does this circuit functions with pure DC?
