- How to choose capacitors, zener diodes and resistors for a circuit that generates radio waves.
I haven't been building electrical circuits for quite a while, but I'm now trying to create a circuit that produces RF random noise. I found this webpage with some information about it.
http://www.n5ese.com/noise.htm
There is this diagram there:
I have an LM324D SMD op amp with pins arranged to this kind of order:
Can I really expect the circuit described on that web page to do what it's supposed to do? And how to choose the capacitances, resistances and zener voltages in the circuit to produce as much RF energy as possible with the given voltage source? It's also a bit unclear to me what I'm supposed to connect to the other input of the amplifier when only one is shown in the diagram. And the length of the conductor in the position termed "RF out" probably affects the effectiveness too.
Thanks in advance for any replies.
