The Binomial Distribution / Binomial Probability Function

The Binomial Distribution / Binomial Probability Function

1 When can you use the binomial formula?

We want to know how many times something does or doesn’t happen e.g. rolling a
die multiple times:

can use binomial if we want to know “number of sixes”
can’t use binomial if we want to know “sum of rolls”

Linear Phase Filtering

“Linear Phase” refers to the condition where the phase response of the filter is a linear (straight-line) function of frequency (excluding phase wraps at +/- 180 degrees). This results in the delay through the filter being the same at all frequencies. Therefore, the filter does not cause “phase distortion” or “delay distortion”. The lack of [...]
