Abcd code is being transmitted to a remote receiver. the bits are a3, a2, a1, and a0, with a3as the msb. the receiver circuitry includes a bcd error detector circuit that examines the received code to see if it is a legal bcd code (i. e., ≤1001). design this circuit to produce a high for any error condition.

these  signals travel  down a part of the neuron called the axon, which is like a wire that carries the  signal  to othernerve  cells. on average a  nerve  cell sends a  signal  at about 50 meters per second, which is over 100  miles  an hour!

no. when the asker posts the question they can make a question worth what ever they think is a fair price. although it must be within the limit of the points they currently own. 5 is the minimum number of points a question can be worth. if a question is complicated or has lots of parts to it, it is better to make it worth more because more people will be more willing to answer.

hope this !
