The EC-796 is an ideal equipment for teaching digital transmission systems.
It allows to cover the theory and practice of the different stages of a transmission system with ease: sampling, quantification, modulation, simulation of channel and reception; essential to lay the foundations for the modern telecommunication digital network.
The EC-796 allows the development of experiments at five levels:
Analysis of the sampling and quantification of analogical signals, with acoustic and visual experimentation of the effect of the sampling frequency (aliasing) and of the number of bits used in the generation of the PCM signal.
Study of digital modulations on continuous wave in amplitude, frequency and phase.
Experimentation of the characteristics of circuit alternatives in the emission and reception modules.
Analysis of the effect of disturbance in the channel (interference, noise, bandwidth and attenuation) on the different modulations.
Experimentation on different means of transmission: coaxial cable, two-wire, infrared, radio and optical fibre.
The EC-796 is presented in stackable desks, very easy to set up, designed both for graphic demonstrations of the theory explained in class, and for the student to carry out very attractive practices with basic instrumentation.
The instruments recommended for operation are a function generator and an oscilloscope.
