f4cepl4nt Posted May 15, 2006 Report Share Posted May 15, 2006 Just a quick question or two.... does the sine wave output of a hartley oscillator (or colpitts or another sinusoidal output oscillator) create AC (does the output voltage go negative)? Or is it just DC with voltage moving smoothly up and down?Also, if I were to take a 1MHz signal from a square wave generator, (a 555 timer or another oscillator that just makes a pulsed DC output) , and transmit that with an EM wave; if I had a series LC filter on the receiving end would that properly pass a square wave(or at least pass a sinusoidal component of that square wave)?Thanks again...had a hard time finding info on these two questions. My guess would be that the LC filter would pass the sinusoidal component of the DC pulsed wave...and the hartley/colpitts/watever oscillator makes pulsed DC. Please inform me if these guesses are correct! =) Quote Link to comment Share on other sites More sharing options...
