    Yes boss, I did work out the dynamic range of that log amplifier we wanted to use in our next product’s sensor PCB, it’s 80dB.

    The results are over here. (points to a roll of A-4 paper)

    It has 40 data points and only took me 1 week, 10 pencils, and 20 erasers to plot the chart. Yeah I can present it, it’ll take me 10 minutes to roll it out, pin it down, and fetch the A-frame ladder.

      This is the real big brain hack with decibels — you can use a linear scale, it’s just that the units are logarithmic instead.

      (Yes I know most people would call a dB axis logarithmic, it’s just a silly comment.)

        You call this a linear holograph of a non linear phenomenon and earn yourself that promotion.
