b) Draw a circuit showing how to use a 74LS138 decoder and a 74LS10 NAND gate to implement the equation F = E(2,5,7). The 74LS138 is an "active-low" decoder and the 74LS10 is a positive logic NAND – remember how to use bubble-matching with NAND gates. In the decoder, Pin G1 is connected to Vcc and the G2 pins are not used (connected to GND). The image on the TI.com datasheet is not very clear, here is a better picture of the decoder: 16
