Digital Modulation Demodulation

With this board the students can study the operating principle of the digital communications using the most common techniques such as PCM modulation, PFM modulation, PAM modulation, PWM and PPM modulations and finally the DM modulation with the aid also of a signal of noise, of analog filters and output amplifiers. The design and construction of electronic circuits to solve practical problems is an essential technique in the fields of electronic engineering and computer engineering.
