- Chapter 1 (Electronics Fundamentals): the BJT and MOSFET we studied are the active devices inside every op-amp, ADC, and oscilloscope front-end. The 1 M scope input uses FETs to achieve gigaohm input impedance from a low-leakage transistor.
- Chapter 10 (Op-amps): every solid-state voltmeter, scope vertical amplifier, signal-conditioning chain, and instrumentation amp is built from op-amps. Knowing input bias current, offset voltage, slew rate, and gain-bandwidth product pays off when reading instrument datasheets.
- Chapter 17 (Signals and Systems): the FFT in your oscilloscope is exactly the FFT we derived. The bandwidth-rise time relationship is exactly the time-frequency uncertainty principle. The sin(x)/x reconstruction is the sinc interpolator from sampling theory.
- Chapter 24 (Hardware Security): you now have the vocabulary to read DPA papers ("we used a Picoscope 6404D, 5 GS/s, 250 MHz bandwidth, captured 50,000 traces..."), and to spec your own attack rig.
