1. Create a VI in LabVIEW to write to DI/0 0 the following sequence repeatedly: 101010000. This will be the character S, followed by .4 seconds of idle. Each bit should be active for .1 seconds and the total sequence should repeat every second. 2. Use an AND gate, derived from two NOT ANDs, to create a circuit that blocks and passes the 20 kHz wave from the function generator. The NAND gate has ground on pin 7 and 5V on pin 14. The signal from the FGEN should be a square wave at a frequency of 20 kHz, with a low voltage of OV and a high voltage of 5V. The U2A and U2B comprise an AND gate, as the first is a NAND and the second is an inverter. When the DI/O line is high, the square wave from the function generator passes through. When the DI/O line is low, nothing should transmit
