Forrest Mims book page 126
Frequency 100-200Hz range
Sim speed impacts frequency???
Negtive pulse for logic circuits
Variable Resistor controls frequency in real world
Do NOT know why Mims used a 10nF cap across pins 1 and 5? You can take it out and it does nothing? Maybe in the real world it is needed for something?
Some circuits have variable capacitors controlling freq. BUT variable resistors cost less $$$
