  • Common misuse of words. Decimate means reduce by 1/10 not almost completely destroy. Exponential growth. The variable has to be in the exponent if it’s a constant exponent that is polynomial growth. Gaslighting isn’t just lying. It’s making someone belive that they can’t trust their own memories or experiences so they believe you despite evidence to the contrary.

















  • It’s Nyquist–Shannon. Norquist is taxes.

    Also frequencies greater than half the sampling rate aren’t lost they fold into lower frequencies unless filtered out.

    But if you think it’s easiser to capture those room acoustics with analog equipment the non linear amplification and distortion of any analog system is going to change the sound just add much if not more then a good digital system.

    So yeah both lose or distort the signal but digital does it in avery predictable way that can be accounted for and it does have a frequency region that it captures precisely. Analog doesn’t.


  • So I got my AA at community college and my bachelors in computer engineering at a university. Other then math and physics there wasn’t a ton of useful classes in CC.

    But if you are going to an ABET accredited school (or similar if outside north america) you are going to learn a lot in university.

    You should learn how to analyze basic RLC circuits. How semiconductors work at a atomic level. How to design basic transistor circuits. Logic gates both design and analysis. Flipflops (the simplest computer). Computer architecture. A programming language or two and some basic assembly. How to use an oscope, logic probe, and multi meter. Basic digital signal processing, fourier transform, and linear controls.

    There is a ton to learn and it’s not stuff you can just pickup on the job.

    Keep at it and good luck.
