Comparators  

The board is divided into four sections for the study of, respectively:
• hysteresis comparator
• zero crossing detector
• window comparator
• amplitude level classifier
The outputs of the comparators are provided with LED to show their electrical state.
The board is supplied complete with a set of stackable, plug‐in cables of suitable lengths and colours and with a training manual.
Power supply: ± 15 Vdc, 750 mA
Experiments
• Analysis and checking of symmetrical and asymmetrical hysteresis cycle comparators
• Analysis and checking of zero crossing detector and window comparator
• Analysis of amplitude detecting circuits with logic output decoding
• Analysis and checking of inverting and non inverting voltage comparators
