Digital Trainer to Verify Half Subtractor using OR, EX-OR and AND Gates (code EL-DEECP-1168) is a digital electronics trainer for verifying the truth table of a half subtractor, the basic circuit that subtracts one binary digit from another and signals a borrow. It is listed with OR, EX-OR and AND gates, and its description also names NOT gates. Jain Laboratory Instruments Pvt Ltd (JLab) makes it at its works in Ambala, India.

What Is the Half Subtractor Trainer Used For?
A half subtractor computes A minus B for two single bits and gives two outputs: the Difference, from an EX-OR gate, and the Borrow, from an AND gate fed with B and the inverted A — which is why a NOT gate appears alongside the EX-OR and AND gates. Stepping through the four input combinations shows that zero minus one gives a difference of one with a borrow, while one minus one gives zero with no borrow. Comparing the result with the half adder makes the point that the difference and the sum are the same EX-OR function and only the borrow and carry logic differ. The trainer is used in B.Sc. electronics and computer science labs, engineering and polytechnic digital electronics courses and ITI electronics workshops.
Frequently Asked Questions
What does this trainer verify?
The truth table of a half subtractor, with the difference and borrow outputs checked for every combination of the two inputs. Its description also mentions the half adder, full adder and full subtractor, so ask JLab to confirm the exact set of circuits on the panel.
Why does a half subtractor need a NOT gate?
The borrow is true only when A is low and B is high, so the AND gate that produces it needs A inverted. The difference output needs only the EX-OR gate.
Which trainer covers all four adder and subtractor circuits?
The Digital Trainer Kit to Verify Adders and Subtractors, linked below, is listed for the half adder, half subtractor, full adder and full subtractor on one panel.
Who manufactures it?
JLab, the trading name of Jain Laboratory Instruments Pvt Ltd, at its works in Ambala, Haryana.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of digital trainers and laboratory equipment in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The half subtractor trainer is built at JLab’s own works rather than bought from a trader, so colleges, institutes, dealers and importers order factory-direct, each unit is visually inspected before dispatch, and repeat orders go straight to the manufacturer. JLab is registered as a manufacturing enterprise under MSME Udyam registration UDYAM-HR-01-0003849 and exports under Importer-Exporter Code 3317504552. JLab exports worldwide and ships to buyers in every region — for example South Africa in Southern Africa, Burkina Faso in West Africa, Portugal in Southern Europe, Iceland in Northern Europe and Chad in Central Africa. Tender details are on the JLab lab tenders page.
