Oscilloscope-Triggered Sweep using 555 IC

Posted on April 25, 2010 by Rust
Oscilloscope-Triggered Sweep

We can use the 555 timer to hold the cost down of adding a triggered sweep to an economy oscilloscope. The timer is triggered by the circuit’s input op amp, adjusting its flip-flop and cutting off its discharge transistor so … Continue reading →
