NOTES: A. When the inputs are open circuited, the output is high. A capacitor may be used for dc isolation of the line-terminating resistor.

At the frequency of operation, the impedance of the capacitor should be relatively small.

B. Use of a capacitor to control response time is optional.

Example: let f = 5 MHz
