sawtooth wave form

[killerwhale007]

hi, can any1 give me idea on how to generate a save tooth wave form using amplifier and reverse the vave form.


/|/| then |\|\ reversed

 

[Styx]

maybe a ripple counter chip with a filter on thte output

Some more details would give a better chance of meaningful answers!, but an opamp triangle wave generator can be made to produce sawtooths either way.

yes but the problem is I would like to have half of saw tooth waveform

like |\ |\ /|
| \| \ then / |

I am using the triangle waveform generator but the it generates like
/\
/ \ I would only like half to the one above but after every 10 cycles I like to reverse it like the one above

 

[Nigel Goodwin]

If you told us what you are trying to do it would probably help?.

u can use an UJT relaxation osc to produce a sawtooth wave .
but is u want a custom waveform better to synthesize it (digitaly?)

hi, I need to use a operational amplifier with counter
I need a simple type of operational amplifier will either gnerate then reverse the waveform

or can you tell me a simple way of reversing the waveform

Nigel and I say: "If you told us what you are trying to do it would probably help."

Do you actually want a Ramp Generator?
It is A Slow increase, than a Sudden Drop?
