What is a micro reflection?
When discussing data transmission over cable networks, we are especially interested in reflections that have very short time delays, on the order of less than a symbol period to perhaps several symbol periods — in other words, close-in or “micro” reflections.
At what frequency does the forward system start?
The forward (or downstream) path is from the cable operator’s headend to the subscriber and is generally from 54 MHz to as high as 1000 MHz. While the upstream is what is returned from every house back to the cable operator’s headend. This frequency range is typically from 5 MHz to 42 MHz.
What is ripple in cable?
2005. Amplitude Ripple/Tilt. • Amplitude ripple and tilt are known in cable industry vernacular as. frequency response, and can refer to in-channel frequency response or. the frequency response across a specified RF bandwidth such as 5-42.
What causes ripple in cable?
These ripples arise due to multiple reflections of the signal travelling within cables, connectors, evaluation board traces, device under test (DUT) and package. These ripples are caused due to impedance mismatch at the junctions of these interconnects.
What is RF ripple?
Editorial Team – everything RF Ripples are the fluctuations (measured in dB) in the pass band, or stop band, of a filter’s frequency magnitude response curve. Elliptic and Chebyshev-based filters have constant ripple across their pass bands.
What is ripple in cable TV?
What causes upstream ripples?
What should my modem frequency be?
A common frequency range for downstream channels (or your download speed) is between 54 MHz to as high as 1000 MHz. For upstream channels (or your upload speeds) the range is 5 MHz to 42 MHz.
Does higher-frequency mean more bandwidth?
Higher Frequencies Have More Bandwidth Higher-frequency transmissions have more bandwidth than lower-frequency transmissions, which means higher-frequency transmissions can send substantially more data between devices in less time. However, more bandwidth only matters if you need it.
What is ICFR in cable?
ICFR stands for In-Channel Frequency Response. ICFR describes the flatness of your 6 MHz digital channel. When the channel is not flat, the digital signal may become distorted and receiving equipment can have a difficult time making decisions about the bits being received.
