Encoder & Decoder Trainer (8:3 and 3:8 Line) Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12767
Indian Lab Suppliers supplies the Encoder & Decoder Trainer (8:3 and 3:8 Line) (Product ID: 12767) as part of its electronics engineering lab equipment range. It verifies the truth tables of an 8-to-3 line encoder and a 3-to-8 line decoder built from basic gates.
Quick Answer
The encoder converts one active line out of eight into a 3-bit binary code using OR gates; the decoder does the reverse, with AND gates and inverters activating one of eight outputs for each 3-bit input. The circuits use AND (7411), NOT (7404) and OR (7432) gate ICs, with eight SPDT switches for inputs and eight LEDs for status. A 5 V DC, 100 mA regulated supply is built in; the unit runs from 230 V ±10%, 50 Hz mains, weighs about 1 kg and measures W 300 × H 200 × D 73 mm.
