Examine a traditional Hartley oscillator circuit, and you’ll note its trademark: a tapped inductor that determines the frequency of oscillation and provides oscillation-sustaining feedback. Although ...

On the figure shown, assume that it is desired to design the oscillator so that its oscillating frequency is 4 MHz. If C3 is adjusted to 300 pF and the desired feedback fraction is B=1/20, calculate: ...

In the summer of 1929, it would probably have been hard for the average Joe to imagine the degree to which his life was about to change. In October of that year, the US stock market tumbled, which in ...
