PWM circuit 555

[pese]

start with 42800
and 2 frequeny 840Hz.
Attn. Keely sai 610Hz (test this also.


SM Ravi and other
using 2 frequencies.

study also drusell kettering

to become an bette feeling
over "waves, resonancees" and more...

Bob Boyce uses 42800, 21400 and 10700 around his toroid.
See chapter 10 (ref above).

tks.
if you give attention of the numbers
10700 time 2  is
21400   this time 2 is:
42800.

if you calculate from my number 840Hz

double double double  9 times
you will also find YOUR NUMBERS !!

So this are all HARMONICs & RESONANCES.

please look Homepage from drusell / kettering university.
aucousic waves
very helpfully to become more feeling to  waves and frequencies

I tremble to suggest that you may be wrong here, Pese, but
I am not betting my kidneys on you being right:
The octaves:
840
1680
3360
6720
13440 (which should be 10700)
26880 (which should be 21400)
