Schematic DIY KitComparator Basic circuit of the signal processing
The comparator is a frequently used sub-circuit in the analog signal processing.
He compares two input signals, and depending on whether signal A is larger than signal B, or vice versa, changes the output signal. A comparator compares (engl Compare) so, just two signals. This example, simple two-step control are possible. Closely related to the comparator are Schmitt trigger and window discriminator.
