Thus, circuits were devised that would reasonably simulate those characteristics of the network that affect the CPE operation from a network harm viewpoint. The simulators are illustrated in Section 1 of TIA-968-A. They simulate the dc voltage and resista ...

A Custom built UHF to VHF downconverter
... of the digital part of the PLL was also used as the power supply for the VCO. The “filtered” VCO power supply (Q4) did not allow the PLL to lock at its programmed frequency. The rest of the components are soldered and tuned for optimal gain and NF. The total cost of the project is in the range of R3 ...

Phase Relations in Active Filters
... Filter complexity is typically defined by the filter “order,” which is related to the number of energy storage elements (inductors and capacitors). The order of the filter transfer function’s denominator defines the attenuation rate as frequency increases. The asymptotic filter rolloff rate is –6n d ...

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.
