On the terms "lossless" and "lossy" compression
I will be speaking here of data compression in the sense of taking a suite of data that describes s thing and replacing with with a smaller suite of data that describes the same thing (perhaps "exactly"...

The correctness of data you the TIFF and the Quality 5 has 36% fewer .
In both cases data is lost, of course.
In both cases data is lost, of course , is "lossy", while another doesn't.

The easy little kit
This chip has Fet output built in, so it doesn't need lossy resistors at the output for paralleling.
Making two chips as easy as one.
This is documented in the TDA7293 datasheet as a modular approach.

If we compare image procesing of the losslessly compressed images with the image processing of the lossy compressed images, does the latter provide the results comparable to the former one.
