Functional Blocks Generic Circuit System Source Transfer Function Load Generic Circuit System Source (voltage plus resistance, as in Thevenin Equivalent) Intermediate Circuit (characterized by a transfer function … filter, amplifier, etc.) Load (resistance, capacitance, inductance or combination) Voltage divider for Zin and Zout
Adding Functional Blocks Adding Functional Blocks to a Circuit can Radically Change What the Circuit Does Potential Issues Check input and output impedances to be sure independent functions work together Check input and output voltage, current, power to be sure that they are adequate Voltage Divider Video 6.1 (Designing Circuits from Functional Blocks)
