question archive Electronics (a) What is the time constant of an RC circuit when R = 1000 ohms and C = 1 nanoFarad? What possible use would there be for such an RC circuit in experiments? Are there several ways to configure the RC circuit for different purposes? (b) Why do we often terminate a shielded BNC signal cable with a 50 ohm terminator on each end? What does the 50 ohm terminator do in terms of the speed of the electronic circuit that involves the cable

(a) What is the time constant of an RC circuit when R = 1000 ohms and C = 1 nanoFarad? What possible use would there be for such an RC circuit in experiments? Are there several ways to configure the RC circuit for different purposes?
(b) Why do we often terminate a shielded BNC signal cable with a 50 ohm terminator on each end? What does the 50 ohm terminator do in terms of the speed of the electronic circuit that involves the cable. Why is 50 ohms chosen, rather than some other value?
(c) An operational amplifier can be configured to give gain. Draw this circuit and explain why the op amp has gain when configured this way. What circuit elements determine the exact value of the gain and why?
