The Why and How of Differential Signaling
In order to get higher data rates, less power consumption, less charging capacitance, etc., you reduce the voltage of the differential signal. If you lower the voltage, your snr gets smaller. In analog audio application, it''s a different approach. You want to have a high snr and you don''t intentionally want to reduce it, because you loose ...

Discharging. Discharging a capacitor through a resistor proceeds in a similar fashion, as illustrates. Initially, the current is I 0 =V 0 /R, driven by the initial voltage V 0 on the capacitor. As the voltage decreases, the current and hence the rate of discharge decreases, implying another exponential formula for V.

How do you find the voltage across a capacitor at time t= 0 and t ...
Once you know t the voltage on C can be more easily calculated. The voltage on C will change by 63% of the applied voltage (applied across RC) after each t time period. This works for charging or discharging. (In discharging you could say the voltage is at 37%, however this is the same as saying a 63% decrease.)
