Hi,
I'm stumped with the following problem: I have an arbitrary 0-5V waveform which ranges between 2 to 30 Hz and which I would like to translate to -60 to +60 V. The translated voltage feeds a constant resistive load which will draw 10mA at the peaks (ie at +/- 60V).
I've simulated (in LTSpice) amplitude modulating a 30 KHz square wave with this arbitrary waveform, then using a step-up transformer with a split secondary to amplify the voltage, then rectifying the secondary outputs to demodulate back to the lo-frequency signal but that cannot give me the required bipolarity.
Some help please!
