Electronic Circuits VIII: Phase, Impedance, and Active Filters Step by Step
A lightweight execution-visualization book.
Phase as Timing
Phase Is Time Shift Over Period
Lag and Lead Are Directional
Cutoff Phase Is a Named Model Point
Impedance Triangles
Resistance and Reactance Form Impedance
Current Uses Impedance Magnitude
Reactance Ratios Come From the Triangle
Loading and Buffers
Impedance Divider Sets Load Voltage
Lower Load Impedance Pulls Output Down
Buffer Isolates the Filter Load
Active Filter Contracts
Active Filter Separates Ratio and Gain
Rail Limit Is Not a Filter Ratio
Phase Filter Audit Closes the Chain
Phase and Impedance Cross Scans
Phase Fraction Three-Row Scan
Impedance Current Three-Row Scan
Same-Phase Divider Three-Row Scan
Source-Factor Depth Scans
Phase Period Three-Row Scan
Source Voltage Through Impedance Three-Row Scan
Source Impedance Divider Three-Row Scan
Passive Ratio Three-Row Scan
Active Gain Three-Row Scan
