hz range frequency sine wave oscillator?
« on: July 21, 2008, 07:01:55 am »
i have taken an extra interest into the frequency of 8hz and the natural earth frequency of 7.82hz and would like to try out a mini elf magnetic field transmitter experiment...if r1 is left at 1,000 ohms (1k) and r2 is left at 1,000,000 ohms (1M)and the capcitance is 1x10^-7 farads (.1uf)...does this mean my starting frequency will be 7.24 Hz according to the equation?...check out this site to understnad my babble.

ONE OTHER IMPORTAnT would i change the wave form to a sine wave instead of the square wave?...use ac current? but what is the point then of pulsing ac current?...or is there a way to some how take ac current and step it down to a frequency of 8 hz?? this is over my head....

jsut found this also...might go with this method converts the initial square wave to a sine wave.
