Basic Filter Theory Review
... Since outputs are being summed and since one filter will be producing output voltage of much grater amplitude for frequencies on either side of f0, two passbands are produced To produce predictable response, both filters should be of same order with same response shape (usually Butterworth) Q is det ...

... Increasing the VCO frequency • The VCO now has to operate about 2Mhz higher than before. • Either - Reduce the capacitance or the inductance. • Inductance - Only 5 turns! So one turn would probably be too much. • Capacitance – Removed the tiny capacitor in the base of the coil. Added a small 1-28pf ...

In our case, it is preferable to perform the time domain simulation over a large time (50ns) which will give a high precision at low frequencies (From DC to 5GHz), but limit the Fourier spectrum to around 10GHz.

Ringing artifacts
In signal processing, particularly digital image processing, ringing artifacts are artifacts that appear as spurious signals near sharp transitions in a signal. Visually, they appear as bands or ""ghosts"" near edges; audibly, they appear as ""echos"" near transients, particularly sounds from percussion instruments; most noticeable are the pre-echos. The term ""ringing"" is because the output signal oscillates at a fading rate around a sharp transition in the input, similar to a bell after being struck. As with other artifacts, their minimization is a criterion in filter design.
