Consider the circuit in Figure. Neglect base currents.

Determine all resistor values such that the following specifications are satisfied:

logic 1 = 0 V and logic 0 = -1.0 V; VR is the average of the logic 1 and logic 0 values; iE = 0.4 mA when QR is on; i1 = i2 = 0.4 mA; i3 = 0.8 mA when vOR = logic 1; and i4 = 0.8 mA when vNOR = logic 1.
