Re: [TCML] DRSSTC minimum tone frequency

Dorian,

At 1500mS (1.5 Seconds) you should hear individual pops for each burst.
Exactly the same as you would with a speaker playing short DC pulses at 1.5 second intervals.
If you are hearing anything else, you are getting multiple triggering of the burst, possibly a sign of noise getting in to your trigger circuit.

Hi,

Has anyone observed cracking/popping noises for musical notes played on a drsstc if they happen to fall below a certain frequency? Any note with a period of less than 1500ms seem to create an awful rustle on my DRSSTC (popping noise). All waveforms seem to settle down/die out 300us after every burst, so I'm wondering if this is a characteristic of plasma breakouts and not a handicap in my design?

Many thanks.

Dorian
