The design and construction of electronic circuits to solve practical problems is an essential technique in the fields of electronic engineering and computer engineering. Therefore, it is necessary for students to acquire an in-depth knowledge of all the basic circuits, such as amplifiers, oscillators, filters, converters, and then to test their knowledge through simple, but important applications in the field of process control and PID techniques. The products described in this section give students all that is needed to start their first steps in this fascinating world of Electronics. Linear circuits, digital circuits, logic gates, significant applications coming from the real industrial world, all explained in a simple, gradual way through a combination of theory and experiments. De Lorenzo offers two different versions, one that consists of closed panels, of very robust construction and clear serigraphy on the front, and another one composed of open boards with components at sight and provided with CAI software.
