hi people ...
i have a question about speaker signals ... I mean what signal shape that when applied to a speaker causes it to produce recognizable voice (i.e., tone or police sarien)
I tried to apply a 5V DC, but i got continous noise zzzzzzzzzzzz
I tried to apply ramp signal, but I heared the same noise but the sound got louder as the voltage increases ...
can anybody help ..??
