The circuit shown in Fig. 19–95 is a primitive 4-bit
Chapter 19, Problem 5SL(choose chapter or problem)
The circuit shown in Fig. 19-95 is a primitive 4-bit digital to-analog converter . In this circuit, to represent each digit \(\left(2^{n}\right)\) of a binary number, a "1" has the \(n^{t h}) switch closed whereas zero ("0") has the switch open. For example, 0010 is represented by closing switch
, while all other switches are open. Show that the voltage
across the \(1.0 \Omega\) resistor for the binary numbers 0001,0010 , 0100 , and 1001 (which in decimal represent
follows the pattern that you expect for a 4-bit DAC. (Section 17-10 may help.)
