7. 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

8. 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
