BLOCKING OSCILLATOR

[edit] Blocking Oscillator.

I wonder where the base current in this diagram comes from. Are we to suppose that the capacitor has some leakage current? Surely a time constant involving R and C would be appropriate here. Please comment on this somebody. --Technut 10:41, 28 September 2006 (UTC)

[edit] Base Current

The base current comes through a resistor which is not shown in this simplified schematic.

for monostable operation the resistor goes from the base to the emitter (and trigger input goes to the base) for astable operation the resistor goes to the centre tap of the transformer, or across the capacitor.
