Quantização Tangível: Modelos em CNC para o Ensino de Processamento de Sinais

The disciplines of the engineering curriculum require mathematical reasoning and a high degree of abstraction, requiring new approaches that increase student stimulation and interest. This article presents a teaching kit for teaching quantization in disciplines that involve the concept of signal digitization. The prototype was manufactured using a Computer Numerical Control (CNC) and accessible materials, such as MDF and acrylic. As a result, benefits were found from its use in the teaching-learning process, according to the validation form applied.
