    Hello! Sorry about my english is not quite good.

    I'm a new user in this forum. I'm not very good at electronics but I like to make simple experiments with this subject and learn too.

    I would like to know if someone can help me how to find a circuit in the web to produce delta state between 0.5 and 3.5 cps.

    I would accept examples if someone knows how to make it.

    Thanks. I'll wait for your answers.

    I think you may be looking for an oscillator to give frequencies of about .5 - 3.5 Hz (a Hertz is a unit that has replaced Cycles Per Second as the unit of frequency).

    If that is a sine wave oscillator, look at the circuit at the link - http://www.zen22142.zen.co.uk/Circuits/Testgear/sinegen.htm

    You can eliminate the smaller capacitors, and slow the frequency down to your range by using two 10 uF capacitors in place of the two 1 uF capacitors. That should let the oscillator run from 1.5 - 15 Hz. A little fast, but easy to make.
