MT1 to MT2|51 SCTE Final TEST 2025
True/False: Audio and Video information are impressed on an RF carrier by a process called Modulation.
- ✔ ✔ True
What is the return path spectrum used by a non-EuroDOCSIS sub split architecture? - ✔ ✔ 5-42 MHz
RFoG mini Nodes typically have two F-connectors. One is for RF and may be used to apply power. the
other is for: - ✔ ✔ Power Only
This is a ______ distortion. (house with car with waves coming from top of pic to bottom of pic) - ✔ ✔
second order distortion
Slowly moving horizontal bars in an analog television picture are typically caused by: - ✔ ✔ Hum
modulation
the frequency response test checks the impedance math of all ports on active device. - ✔ ✔ False
Digital video compression of the digitized video decreases the data rate or bandwidth by: - ✔ ✔
removing redundant information
Which of the following is a disadvantage of using hubs within an architecture? - ✔ ✔ increased
power requirements
True/False: The HFC is similar to the coaxial topology except that long trunk runs are replaced by twisted
pair copper. - ✔ ✔ False
How is the channel frequency response (ICFR) calcualted from pre-equalization coefficients? - ✔ ✔
by taking the Fast Fourier Transform (FFT) of the coefficients
True/false: Excessive intermodulation, low C/N or hum in a downstream digital signal typically will cause
the picture to macroblock. - ✔ ✔ True
what is upstream frequency range for a high-split architecture - ✔ ✔ 5-200 MHz

amplitude inequality
Which of the following is NOT provided by proactive network maintenance technology? - ✔ ✔ Group
delay
When looking at the constellation of QAM signal, the area in which each point of the constellation falls is
called a _________ area. - ✔ ✔ boundary
