... In Figure 6-4, the capacitance of varactor diode D1 and L1 form the parallel tuned circuit of the oscillator. The value of C1 is made very large so its reactance is very low. C1 connects the tuned circuit to the oscillator and blocks the dc bias on the base of Q1 from being shorted to ground through ...

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.
