3.27 Consider the 4 x 4 switch shown in Figure 3.66 made up of 2 x 2 switches. Suppose each 2 x 2 switch has crosstalk suppression of 50 dB. What is the overall crosstalk suppression of the 4 x 4 switch? Assume for now that powers can be added and that we do not have to worry about individual electric fields adding in phase. If we wanted an overall crosstalk suppression of 40 dB, what should the crosstalk suppression of each switch be
