hi
I am designing a Morse Code demonstration system
and need to produce an audio signal for it.
I don't know how design this audio interface.
My logic output is Morse Code at TTL voltage level .
(Dot : 100 ms High 100 ms Low--- Dash : 350 ms High 100 ms Low)
Should i produce pulse or sine wave on this levels for producing audio ?
Should i use speakers or buzzers or anything else ?
Please give me a hardware solution.
Thanks for your support.
