A sequential circuit has an input (X) and two outputs (S and V). X represents a
4-bit binary number N which is input least significant bit first. S represents a 4-bit

the fourth input occurs, V-1 if N +2 is too large to be represented by four bits;
otherwise, V = O. The value of S should be the proper value, not a don't care, in both cases. The circuit

The working hours of a factory are 8 hours a day, divided into three shifts: from 8 to 11 (first shift), from 11 to 13 (second shift), from 13 to 16 (rest) and from 16 to 19 (third shift). It is intended to design a circuit that has as inputs the binary representation of the current hour minus eight and that provides the output of the shift number that is working (if applicable) or "0" if it is break time. It is requested: - Express the minimal output and implementation functions as a sum of products and as a product of sums. - Obtain the expressions corresponding to each of the previous functions carried out with a single type of doors.
A combinational circuit has three inputs (C,1,,1o) and two outputs (01,00). The function is implemented as the following: If C = 0, then O,00 becomes I, 1o. If C = 1, then O,0, becomes (1,11)+1. For example, if C = 1 and 1, is 01, 0,0, becomes 10. Note that, if I, 1, is 11 and = 1, then the output value wraps around 00, without any overflow. %3D F Oo The Boolean expression for 01 and O0 and in sum of minterms form are: Select one: None of the above.

The Amplitude Modulation (AM) is a technique used in communication for transmitting information via radio carrier wave. AM works by varying the amplitude of the transmitted signal in relation to the information being sent.
