Parallel Adder and Subtractor Trainer Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12761
Indian Lab Suppliers supplies the Parallel Adder and Subtractor Trainer (Product ID: 12761) as part of its electronics engineering lab equipment range. It demonstrates parallel binary addition and subtraction of 4-bit and 8-bit numbers.
Quick Answer
In a parallel adder all bit pairs are applied at once to a chain of full-adder stages, and the result settles once the carries have passed through the stages; subtraction uses the complement of one number with the same hardware. Logic switches with LEDs set the inputs, a switch changes between addition and subtraction, and LEDs show the result and carry out. The trainer runs on 5 V DC logic (5 V = 1, 0 V = 0), weighs about 1 kg and measures W 340 × H 125 × D 210 mm. Please confirm the mains supply at quotation.
