Design Content Description
Approach:

Approach: The design skills are developed and tested through a number of homework problems such as:
* design of signal samplers so that the periodicity of a signal is preserved after discretization
* determining personalize drug injection rate that guarantees given steady-state drug concentration
* determining hormone's loss rate constant given concentration at different points in time
* design a pendulum clock so that its oscillation period matches the specifications
* design a strategy for glucose intake that will prevent pre-diabetic response
* design a feedback controller to stabilize an open-loop unstable system
* determining parameters of the transfer function given its Bode plot
* design a low-pass filter that attenuates particular high-frequencies from a signal with a specific attenuation factor
