Scalable White Noise Generator

4-bit sample is pseudo randomly generated using the LSB of 8-bit LSFR (1,2,3,7) at 256Hz. The output is LPFed at nyquist frequency to remove the harmonics from the DAC output. In this configuration there are 256 sample sequence which is spread into a second, which has a 128Hz worth of noise bandwidth for 1 second window. You can increase the sample rate but it will narrow the noise bandwidth, so you also need to increase the number of generated random sample sequence.

That's how you generate white noise lenny.

after 2^5-1=31 clock cycles it starts all over and one periode fits on one EC scope screen. In this length its more a sound generator, needs a much longer shift register, starts being interessting form more then 24 bit shift length. every 300 ms the sequence would repeat and i would start with maybe 32bit and 80s sequence. But @prinzrainer you can add that as note into your description. Lenny anything you have to add? You are so silent.

I was thinking of extending the LFSR.

Only chua can provide true random,, otherwise just sudo random. No!?

Using 32-bit LFSR is too heavy for EC.

you get 4 bit with every counter modul available here, this save a little space and some wiring

and is much much faster

@prinzrainer. With EC basic gates and flip flops, you'll have lag issues with registers over 8 bit.

here a 64bit version, check description http://everycircuit.com/circuit/5410364452503552

Way to go hurz, now that's pushing EC! Looks like you can up the clock more

This certainly is another variation, well done.

Lenny, your way is also correct, why dont you know that and fight for it in your circuit, cause you really dont know its fine! Now you have something correct and @prinzrainer is wrong, and you dont see it. Normaly i tell you if you are wrong, here its the other way around, you are right and the user critique is wrong, funny. This doesnt let you go free as charlatan, you are still unkown, you do not know your circuit will work, maybe a little finetuning is needed. Anyway, because you do not know what you publish, you are not able to fight for it, cuz you do not understand and thats the reason YOU CANT HANDEL CRITIQUE, DOESNT MATTER IF RIGHT OR WRONG CRITIQUE. YOU JUST DONT UNDERSTAND.

I appreciate variation and I don't have to fight for the same things that you fight for. But do what you do best, keep guessing and posting condescension.

you dont understand. Fight wasnt the topic. the topic is your charlatanism. You cant handel critique doesnt matter if its right or wrong, positive or negative. you just dont understand it cuz you do not understand electronics. you proofed it here again. Do you understand?

Keeping guessing and posting condescension my friend...😎

i say charlatan and you make it to something condescening? Oh, Lenny, i think we can see your very little to zero knowledge in electronics as fact. To many discussion to many times you trapped. To many times you had no answer or a wrong one. But the fact you dont see that makes you also a charlatan. Sorry, latest example you come with transistor tester for beginners and we see its a simple one which is soooooo simple it needs an expert to use them and do interpretaions about the results. You trapped again. So many time again and again. If you keep your expert fasade/cover you are unfortunately also a charlatan to who nobody can say anything condescening!

He only finds it condescenating because he is a charlatan.

This is his way of being condescending. He tries to lift himself. Im sure there are not many real friends 24/7 here on EC 365 days a years. Hes a poore guy
