ACL-FIL: Filters/Noise and Audio Amplifier Kit
About Product
The ACL-FLS Filters, Noise & Audio Amplifier Kit enables students to perform practical experiments on noise generation, S/N ratio measurement, and frequency response analysis. It integrates multiple filters, a noise adder stage, and an audio amplifier with a speaker for hands-on understanding of real-world communication system behavior.
1) Designed for practical study of filtering, noise and audio amplification.
2) Demonstrates how different filters select, pass or reject frequency components.
3) Allows observation of the effect of noise on signals.
4) Provides signal conditioning and filtering before amplification.
5) Mobile based interactive e-manual
