The ETB-173 Active Limiter trainer is designed to demonstrate the principles of signal limiting using operational amplifiers and diodes in an active configuration. This experiment allows students to understand how amplitude clipping or limiting can be achieved to protect circuits from signal over-voltage and to maintain output within a desired range.

The setup uses active components such as OP-AMPs along with diodes to limit the signal actively, unlike simple passive clippers. The model comes complete with a regulated power supply and 1 analog meter (C.R.) for real-time measurement and observation of the input-output waveform behavior.

This trainer is essential in analog electronics labs for studying waveform shaping and signal conditioning, particularly in communication systems, audio electronics, and protection circuits.
