? 8 cxa1726am/as input signals description of operation multiplier the input x and y signals of the multiplier are multiplied and output to the out pins. operational amplifier this inputs the signals which have been output from the multiplier. * care is required with ringing in the operational amplifier. placing a 5p capacitor in parallel with the feedback resistor is recommended as a preventive measure. switch the signal input from in1 is selected for "a" side or "b" side by the sw1 applied voltage. when sw1 is 2v or less, low turns to "a" side; it is 2.6v or more, high turns to "b" side. the unselected output pin is connected to gnd. * for the multipliers with a switch, "a" side or "b" side is selected under the same conditions. f = 2 0 0 k h z 3 v p - p g n d g n d 5 v p - p f = 1 m h z s g 1 s g 2
