dprint VS gnuradio

Currently, I am using ESLint for formatting of basic things like spacing and quotes. However, those rules were deprecated with v8.53.0 and moved to @stylistic/eslint-plugin. But they recommend Prettier or dprint.

Prettier is opinionated. dprint is highly configurable.

I mean, I know I am a bad person because of those long names, but that is how life goes sometimes! And the blank line there at the top is just very important to like, catch one's breath, while reading this code.

(I'm really just posting this in the hopes that somebody will throw me a "Bro, just use hpstrlnt, it totally lets you configure that!" -- I have not actually tried Rome to see if it does (it's Monday morning and I'm not quite ready to be disappointed again...))

[1]: dprint is good, and I recommend it as the best code formatter I currently know of: https://dprint.dev/

If it's something in the vein of one of those things then, worst case, you generate the code first, then run it through something like dprint.

Why not compare Rome formatter to the actual competition, https://dprint.dev/ ?

In gr-dtv transmitter examples for Gnuradio, I see some times people use a resampler block before the RF hardware sink. Say our sampling rate is ~9.14Msps which satisfies the Nyquist criterion because our samples are complex numbers.

2.1. Thanks for that tip, I forgot that I was able to check the source code of the WBFM Receive block. As you have said, there are mostly the same. There are some differences between how values are picked. The WBFM Receive block would be a synonym of Quadrature demod => Fir Filter (decimation => Low pass filter) => FM Deemphasis. 2.3. My question there is why 10 and not 20 or 100. I understand that the idea is to reduce the sample rate asap, but what I don't understand is why those values were picked and how can I understand what would be the "correct" or "best" value. 2.4. I'm not fully understanding what you said. If I check the WB FM recieve source code the values that are supplied as the cutoff freq and transition width of the Low pass filter differ from the one of the example. The webfm would apply a sample rate / decimation / 2 - sample rate / decimation / 32 as a cutoff freq and a sample rate / decimation / 32 as a transition transition width. Calculating those values would end up in different that the ones supplied in this second example. Again, is there a rule of thumb to pick these values?.

Gaussian filter is used only on the tx side, so specifying bt in the receiver makes no sense. Take a look at gfsk mod/demod blocks implementation: https://github.com/gnuradio/gnuradio/blob/master/gr-digital/python/digital/gfsk.py

GNU Radio

Here's the filter coefficients used for the GNU-Radio interpolator block to get you started. This is a 7th order interpolator (i.e., 8 FIR taps) with very good performance. Each "row" of the array sets the delay in steps of sample_time / 128.
