Ohm's Law - answer V = IR
Time Constant - answer τ = RC
TIme constant is the time it takes for the capacitor to charge to 63%
of maximum. It takes 5 time constants to reach maximum.
Cutoff Frequency - answer f(cutoff) = 1/2 πτ = 1/2 πRC
The cutoff frequency of a filter is inversely proportional to its time
constant. A long time constant means a lower cutoff and a short
time constant means a higher cutoff.
Gain - answer Gain = Output voltage / Input voltage
Sensitivity - answer Sensitivity = Input voltage / Vertical deflection
(in divisions or mm)
Horizontal Resolution - answer Bin Width = 1 / Sampling Rate (data
points per second)
Vertical Resolution - answer # of available voltage values = 2^N
where N = number of bits
Signal to Noise ratio - answer SNR(N) = SNR(initial) * N^1/2
where N = # of averages
