Guys,
I know it's totally a stupid question here...
I am generating a 50-50 duty pulse wave at 1MHz. Thus it will give me a 500KHz Oscillation. (that's what i want, a 500KHz carrier). Now, as I'm generating it from CMOS, the OSC is in the range of 0-5v. It's not AC type, instead a pulse only. To make it +/- voltage like OSC, i am planning to scale the 0 voltage to -5. Thus +/- 5V OSC. Any ideas??? [I'm using arduino].
Also, the other way is scale down the whole pulse to 2.5V, thus 0 will be -2.5, 2.5 will be 0 and 5 will be 2.5.
But still, I prefer the +/-5V option.
