RE: [TCML] Audiotesla MKIIc Xpression

["Dr.Hankenstein" <dr.hankenstein@xxxxxxxxxxxxx>]

Josh,

Bit rate on a DRSSTC usually refers to the number of times per second
the coil is triggered, i.e.: a bit rate of say 250BBS would sound like a
250 hertz audio tone. The duration, on the other hand, usually refers to
the output transistors "on time" in microseconds. Normally, the longer
the duration, the more power can be transferred from the primary to the
secondary. Changing the duration as expressed above will cause the spark
to be longer or shorter. Perhaps the term "duration" as you mentioned
would better be understood as "run time". One of our runs was estimated
to be in excess of an hour with short rests in between (changing songs!)

Hope that makes more sense.

Regards,
Dr.H

Dr. H
Could you elaborate a bit more on DRSSTC 'bit-rate' and 'duration'?
These term are a bit vauge and could me a lot of things.
Like, the 'duration' of my DRSSTC was about 5 minutes then the cap and
IGBTs
exploded.  =)

Thanks,
Josh
