Dear Students,

Kindly note the following mistakes:

1.  In case of half-adder logic circuit in the problem number 2.1 of week-1 lecture-2 video at 12:51 minutes, sum and carry labels have been exchanged by mistake. The AND gate should be SUM and the XOR gate should be CARRY. Inconvenience is deeply regretted. Students may kindly see the figures attached as correction. 

2.  In case of same lecture video at 24:00 minutes, in the truth table, the value of the variable "signal" should be 0 (zero) in the fifth row of values with combination A = 0, B = 1 and C = 1. It is written 1 by mistake. 


The slides may kindly be seen. Inconvenience is regretted.
