        | 886 | Basic Logic Gates using discrete 
        components 5 in 1 Objective : To verify the truth table for DTL AND, OR, NOT, NAND 
        NOR gates.
 Features : Instrument comprises of 5V/150mA DC Regulated Power 
        Supply for logic '1' logic '0'. Circuit diagram for 'OR', 'AND' 'NOT' 
        gates has been printed components mounted on front panel to demonstrate 
        the working of DTL gates. NAND NOR gates can be assembled using 
        different combinations of Gates.
