What is digital bandwidth finder

Click For Summary
SUMMARY

The discussion centers on the concept of a digital bandwidth finder, which is often confused with digital filters. A digital filter, in microwave technology, refers to a physical structure known as a distributed element filter, used to select specific wavelengths. The conversation highlights the differences between analog and digital filtering, emphasizing that digital filters process stored signals using algorithms like Pulse Width Modulation (PWM). The participants also reference resources such as Wikipedia for further clarification on distributed element filters.

PREREQUISITES
  • Understanding of digital signal processing concepts
  • Familiarity with microwave technology and distributed element filters
  • Knowledge of Pulse Width Modulation (PWM)

Hello,
I was watching this video 07:37 there is instrument called digital bandwidth finder written on it.
what it do?
There is standard dish and High definition dish.
will coaxial wire used with LNB and feed horn are same for both broadcasting?

What video?
 
Confused ?
Bandwidth finder or bandwidth filter ?

A “digital filter” now refers to a numerical algorithm used to process digitised data.
In microwave technology “digital filter” or “interdigital flter” refers to a physical structure “distributed element filter” used to select a band of wavelength. A digital filter has a number of coupled resonant elements that looks like fingers on a hand, all grounded at one end. An interdigital filter looks like two hands with alternate resonators connected at opposite ends, like two hands with interlaced fingers.

Bandwidth finder yes

Hello,
In analog signal filter mean at different frequency it is modulated.
But in case of Digital how filter work?
The signal is stored in memory and modulated by PWM i thinkhere is the video
