How Does a Capacitor Introduce Phase Delay in a Circuit?
Click For Summary
SUMMARY
The discussion focuses on measuring phase delay introduced by capacitors in circuits using LTSpice simulations. It emphasizes that phase delay, or phase lag, is best analyzed with sine waves rather than square waves due to the frequency dependence of the delay. The participants clarify that transient analysis is not suitable for observing frequency domain characteristics, recommending a different SPICE analysis mode for accurate results. Understanding the input waveform conditions is crucial for meaningful phase delay measurements.
