Create a SubVI that multiplexes four inputs (a, b,c, d) into a single output. The subVI should have four floating-point numeric controls (denoted ln1 thru ln4), one floating-point numeric indicator (denoted by Out), and one uinsigned 8-bit integer control (denoted by Select). If Select=1, then Out = ln1; if Select = 2, then Out = ln2, Select = 3, then Out = ln3, Select=4, then Out = ln4.(Hint: The select function VI from the programming>> Comparison palette may be useful.)
