Z-Transform - Practical Applications - Phil’s Lab #27

Covering practical applications of the Z-transform used in digital signal processing, for example, stability analysis and frequency response of discrete-time systems. Theory, C code, and implementation on a real-world embedded system (STM32 microcontroller). Free trial of Altium Designer: Visit for $2 for five 2-layer PCBs and $5 for five 4-layer PCBs.
