Phase and Impedance Cross Scans

Phase Fraction Three-Row Scan

lag over period

Holding period fixed makes phase a scan of lag divided by period. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

Three seconds of twelve is one quarter cycle

Period 12 seconds and lag 3 seconds give phase 1/4 cycle.

Six seconds of twelve is one half cycle

Keeping the period at 12 seconds, lag 6 seconds gives phase 1/2 cycle.

Nine seconds of twelve is three quarters cycle

Lag 9 seconds over period 12 seconds gives phase 3/4 cycle.
