Resumen
This paper presents the design of a digital oscilloscope for signals up to 4MHz with support for FIR and IIR filters in real time and spectral analysis. It is a monochannel oscilloscope that can be expanded and brings the features typical of this category of equipment, with the characteristic of having a very low cost, making it possible to build practical and accessible to students of technology, engineering or electronics technicians. The analyzer / oscilloscope works at a setting of virtual instrument, that is, emulates a real equipment through a circuit connected to a personal computer through its USB port. The design was implemented in Matlab language and is based on a module arduino connected to a data acquisition card which allows the analog to digital conversion at a rate of forty million samples per second.
