1. Circuit Analysis and Design
Spec area 1, 10 to 15 of 85 questions: passive and active components, DC circuits, AC circuits, transient analysis, and battery characteristics and applications.
Key facts
- Thevenin and Norton equivalents reduce any linear network to one source and one impedance; maximum power transfer occurs when the load equals Rth (or the conjugate of Zth for AC), giving Vth² / 4Rth.
- First-order transients: x(t) = x(∞) + [x(0) - x(∞)] e^(-t/τ), with τ = RC or L/R.
- AC phasors: Z_L = jωL, Z_C = 1 / (jωC); real power P = Vrms Irms cos θ.
- Series RLC resonance at f0 = 1 / (2π sqrt(LC)); Q = f0 / bandwidth.
- Battery capacity is in ampere-hours; usable capacity falls at high discharge rates (Peukert effect) and low temperature.
- Use nodal or mesh analysis for multi-source networks and superposition for independent sources in linear circuits.
Flashcards
Exam tip: Find the Thevenin equivalent first on most circuit questions. It turns long multi-step problems into one divider.
2. Measurement, Instrumentation, Safety and Reliability
Spec areas 2 and 3, 10 to 16 questions: transducers, operational amplifiers, measurement system design, failure limits and circuit protection, electromagnetic field exposure, safety and reliability analysis (MTBF, tolerances).
Key facts
- Quarter-bridge strain gauge output is about Vex x GF x strain / 4 for small strain; half and full bridges give 2 and 4 times that.
- Ideal op amp: inverting gain -Rf / Rin, noninverting gain 1 + Rf / Rin; the inputs draw no current and sit at the same voltage under negative feedback.
- Instrumentation amplifiers give high common-mode rejection for small differential sensor signals.
- Constant failure rate: R(t) = e^(-λt) and MTBF = 1 / λ; series failure rates add.
- Parallel redundancy: R = 1 - (1 - R1)(1 - R2).
- Thermocouples need cold-junction compensation; RTDs use the change of resistance with temperature.
Flashcards
Exam tip: Reliability questions are mostly exponentials. Do not use 1 - λt unless λt is very small and the answer choices allow it.
3. Signal Processing
Spec area 4, 5 to 8 questions: sampling theory, transforms and applications, analog-to-digital and digital-to-analog conversion, filtering, and signal processing system analysis and design.
Key facts
- Sample at more than twice the highest frequency; content above fs / 2 aliases to |f - n fs|.
- N-bit converter step size is full-scale range / 2^N; maximum quantization error is half a step.
- Ideal quantization SNR for a full-scale sine is about 6.02N + 1.76 dB.
- Laplace transforms analyze continuous systems; z-transforms analyze discrete-time systems; the DFT/FFT gives a sampled spectrum with resolution fs / N.
- FIR filters are always stable and can have linear phase; IIR filters achieve sharp responses with fewer coefficients but can be unstable.
- A first-order RC low-pass filter has its -3 dB point at fc = 1 / (2πRC) and rolls off at 20 dB per decade.
Flashcards
Exam tip: Write fs / 2 on the note board for every sampling question before reading the options.

4. Digital Systems
Spec area 5, 7 to 11 questions: combinational logic, sequential logic, logic devices, and programmable logic devices such as microcontrollers, embedded systems and PLCs.
Key facts
- Simplify with Boolean algebra or Karnaugh maps; De Morgan: (AB)' = A' + B' and (A + B)' = A'B'.
- Maximum clock frequency = 1 / (tcq + tlogic + tsetup) on the critical path; hold time limits the shortest path.
Flashcards
Exam tip: Timing questions often include a hold time to tempt you. Only setup enters the maximum frequency.
5. Electromagnetics and Fiber Optics
Spec area 6, 5 to 8 questions: electromagnetic properties of materials, waves and propagation, electromagnetic compatibility (shielding, grounding, filtering), transmission lines and waveguides, antennas (gain, link budget) and optical fibers.
Key facts
- Free-space path loss (dB) = 20 log d(km) + 20 log f(MHz) + 32.44.
- Link budget: received power = transmit power + antenna gains - path loss - other losses, all in dB terms.
Flashcards
Exam tip: Keep link budgets entirely in dB and dBm. Mixing linear watts with decibels is the most common error.
6. Electronic Components and Circuits
Spec areas 7 and 8, 13 to 20 questions: diodes, transistors and solid-state devices, power supplies and converters, power amplifiers, device models, networks and filters, nonlinear applications, frequency response, transients, and power, energy and heat dissipation.
Key facts
- Zener regulator: series current = (Vin - Vz) / Rs; Zener current = series current - load current; check worst case at no load.
- Junction temperature Tj = Ta + P x (θjc + θcs + θsa).
Flashcards
Exam tip: Thermal questions are Ohm's law with temperature as voltage and power as current. Draw the thermal resistances in series.
7. Analog and Digital Control Systems
Spec area 9, 8 to 12 questions: block diagrams and signal flow graphs, characteristic equations, frequency response, time response, stability (tests, Bode plots, root locus, transport delay) and digital control systems.
Key facts
- Negative feedback closed loop: T = G / (1 + GH); the characteristic equation is 1 + GH = 0.
- Second-order systems: overshoot = e^(-ζπ / sqrt(1 - ζ²)); 2% settling time about 4 / (ζωn).
Flashcards
Exam tip: Identify system type and standard second-order form before calculating. Most control items then take one line.
8. Communications, Noise and Interference
Spec areas 10 to 12, 12 to 18 questions: analog and digital modulation, noise (SNR, quantization noise, noise figure, noise temperature), interference, coding and error correction, wired and wireless systems, multiple access and traffic capacity.
Key facts
- Friis noise: F = F1 + (F2 - 1) / G1 + (F3 - 1) / (G1 G2), with linear values.
- Noise temperature Te = 290 (F - 1) K; thermal noise power is kTB, about -174 dBm/Hz at 290 K.
Flashcards
Exam tip: Convert every dB value to a ratio before using Friis or Shannon, then convert back at the end.
How to pass
- 85 questions in 8.5 hours is 6 minutes each. Bank time on short conceptual items for the long control and electronics calculations.
- Practice with the electronic reference handbook from your MyNCEES account. Searching it quickly matters more than memorizing formulas it already contains.
- Electronic components and electronics circuits together carry 13 to 20 questions, and circuit analysis another 10 to 15. Master these before communications topics with 4 to 6 each.
- The exam runs once a year, so a failed attempt costs a full year. Book your seat early, since single-day exams fill.
