Analog Electronic Circuits

A: Option A would let a real RF-induced gain shift slip through because immunity isn't limited to logic state integrity, Option B misreads an immunity requirement as an emissions control and would ignore nonlinear bias injection, Option C assumes shielding solves everything and misses coupling through bias and control lines, Option D matches the physics of RF rectification in analog nodes and why the standard sets that field strength.

A: Option A can mask a bias sensitivity because the RF sweep happens before you know the bias is behaving, Option B waits too long and lets control loops compensate away the analog symptom, Option C substitutes a regulatory check for a diagnostic step and misses marginal analog behavior, Option D brackets the problem by stressing the analog stage while directly watching the parameter that drifts in the field.

A: Option A underestimates the bandwidth by a factor of 2π and would over-filter the signal, Option B ties the pole to system timing instead of component physics, Option C is a unit slip that shifts the pole by three decades, Option D applies the correct formula and units to land near 1 MHz.

A: Option A ignores that analog edges still have spectral spread, Option B would push you to miss a linear source of emissions seen in the field, Option C drops the spectral-density basis of the limit and would fail at test, Option D aligns with Fourier behavior and why analog design choices affect emissions.
