Someone mentioned the erstwhile multivibrator, is there such a thing, yahoo doesn't have it ?
Subject: erstwhile ??? Hi, Phil. You can check Google for anything in these newsgroups more than a few days old. Looking at the thread, they were talking about an FM transmitter oscillator. I'm not sure what happened to the link, but it's not accessible right now, so I can't say for sure. It seems they were either talking about a Hartley oscillator or a "Kaliatron" oscillator. The second comes up blank both on Google and in the attic upstairs. The use of the word "erstwhile" was a rhetorical flourish someone used to talk about oscillator exposition from memory in one of his theory classes. The word means "former" or "in the past". Good luck Chris
I know this thread, the link is still working ('cause it's mine) Thanks for pointing out that erstwhile is actally a word, I think this poster was trying to confuse me back there. I think it is a Hartley after all.
aaaaaaaaaaaaaaaa posted: << probably not, ignore me. >> If you mean probably not a Hartley, I agree. It's a multivibrator using LC instead of RC. Consider yourself ignored. Don
Phil posted: Don posted So what is the difference between a multivibrator and an oscillator such as Hartley ? >> A significant difference is the the Hartley uses a tap on an inductor to obtain feedback. A multivibrator typically uses a capacitor from each output to the input of it's mirror stage. Google can give you everything you need to know about each. Don

Is a multivibrator the same as an Astable, if so, what is the RC time constant for the circuit in question, and if the oscillation is determined by the capacitors from output to input, how does the tank circuit manage to alter this frequency during the modulation.
