Abstract
In the paper the role of anti-aliasing filters is revised based on control quality assessment of PID controllers when using average sampling versus instantaneous sampling without any analog filter. Numerical results show that contrary to common belief possible benefits gained from anti-aliasing devices are very restricted.
