(D0 = 0, D1 = 0) corresponds to the empty set meaning that the value of D is not yet available. The two rails are mutually exclusive, such that both rails can never be asserted simultaneously; this state is defined as an illegal state. A quad-rail signal, Q, consists of four wires, Q0, Q1, Q2, and Q3, which may assume any value from the set {DATA0, DATA1, DATA2, DATA3, NULL}. The DATA0 state (Q0 = 1, Q1 = 0, Q2 = 0, Q3 = 0) corresponds to two Boolean logic signals, X and Y, where X = 0Proceedings of the 2009 Midwest Section conference of the American Society for Engineering Education 4 and Y = 0. The DATA1 state (Q0 = 0, Q1 = 1, Q2 = 0, Q3 = 0
). Entrepreneurial breakeven point is attained when total income equals totalexpenditure, and income (sales) beyond the breakeven point results in PROFIT. Profit is adesirable condition for entrepreneurial sustainability13-14. “Total sales” is as per equation 1. R=Q.P (1)R is the total sales or revenue, Q is the number of units sold and P is price per unit. Total cost isas per equation 2. TC = FC + VC (2)TC is the total cost, FC is the total fixed costs and VC is variable costs. R = TC (3)Equation 3 represents the “breakeven point” condition. Q.P = FC + VC (4)Eq. 4 results from substituting R from Eq
