[hannibal]

Hi

someone can tell me waht's the difference between "frequency corner" and
"center frequency"
Thank you for your help.

The frequency corner is where schoolchildren go to study frequencies.
The center frequency is how often the term center occurs in a
probability distribution.

Not sure about frequency corner, but corner frequency usually refers
to the 3 db down frequency in a high or low pass filter. Bandpass
filters have a frequency that is either the highest response frequency
somewhere in the pass band, or the geometric mean of the two 3 db down
frequencies on each side of the pass band, called the center
frequency. This also applies (inversely) to band reject filters.

i have heard the term before and it stims from nothing
buy made up electronic slang..
the frequency corner is what you see on the SpectroGraph
is it is dippling downward on either side and is usually
.707 of max peek that denotes the corner. other wise known as
a term to measure band pass etc..

i get really confused with frequencies terminologies.
actually i am working on spreadsheet for Tx so first i am trying to get
familiar with terminologies so i strart with taking a look to Rx spreadsheet
that's alrady done by someone else.
In excel Rx spreadsheet, sometime:
Device frequency corner= Center Frequency+ 1/2 (Device3dB Bandwidth at
output)

and sometime:
Device frequency corner= Center Frequency+ Device3dB Bandwidth at output

i don't know why?
please advice

Probably because someone forgot the 1/2 from the second equation.

Corner--> ------------ <--Corner
