Hello Experts.

 

I've upload the new image files. please can you advise some pointers/links wrt , what's these extension are and some brief info wrt these files please.

 

e.g.

1M_10M_nyq.txt  => 1 Mhz to 10 Mhz  nyq = nyquist => but what is this a chirp signal from 1M to 10M or a ramp (sawtooth) signal
10.txt ? => 10Mhz frequency I guest from the spectrum result
11.txt ? => 11Mhz frequency I guest from the spectrum result
Msk_20M.txt ? Minimum shift keying, 20Mhz frequency I guess?
Sinewave_0.3.mat ? matlab file format guessing a sinewave 300Hz?
Sinewave_0.3_2ch.mat ? matlab file format guessing a sinewave 300Hz in I and Q format?

Filters and file: Would you have any pointers and brief info regarding the spec of these filters. I mean, I know these are GMS, LTE and UMTS standards. But within it there are sub categories e.g. GSM1800, GSM1900, 1G, 2G, 3G, and what does these extension means in the LTEx . Is it frequency, bands, standards or the bandwidth?
