Addressing this issue, Motorola, in collaboration with TV pioneer Sarnoff Corporation, has created a proven, revolutionary digital signal processing architecture known as the MCT2100 demodulator chip that provides excellent signal reception, even under difficult ghost signal
conditions found often in urban areas.
The process of removing an intense signal can result in the unexpected creation of many spurious weak ghost signals
, at any point in the image plane.
Over 200 feet of the run required continuous side-hill locates which almost always result in ghost signals
and false readings.
This new PRISM chip is optimized for use in environments where the signal takes several indirect paths as it bounces off walls or other surfaces and creates delayed ghost signals
that can slow a system's throughput," said Larry Ciaccia, vice president and general manager of Intersil's PRISM Wireless Products business.
In addition, ghost signals
resulting from mode conversions can appear to look like anomalies.
This range allows the chip to remove a greater number of multipath or ghost signals
