ECE Electronic Systems and Technologies (EST) Review (30%)
ECE Electronic Systems and Technologies (EST) Review (30%)
EST is one of the two heaviest ECE subjects at 30%, in the 1–6 PM slot on Day 2. It needs 70% on its own, like every ECE subject.
Suggested practice split
PRC doesn't publish item counts per topic. This is our suggested share of your practice time, not an official breakdown:
| Topic block | Share of practice |
|---|---|
| Analog communications | 12% |
| Digital communications | 15% |
| Networks and data communications | 12% |
| Microwave and satellite | 10% |
| Fiber optics | 10% |
| Transmission lines and antennas | 12% |
| Broadcasting and acoustics | 7% |
| Computer systems, microprocessors, industrial electronics | 22% |
Analog communications
- AM (DSB, SSB, VSB) and FM (narrowband, wideband)
- Receivers (TRF, superheterodyne)
- Noise analysis
Digital communications
- Sampling, quantization, PCM and delta modulation
- Digital modulation (BPSK, QPSK, M-PSK, M-QAM)
- Shannon capacity and bit error rate
- Error correction basics
Networks
- OSI model and the TCP/IP suite
- LAN, MAN, WAN; circuit vs packet switching
- Cellular network principles
Microwave, satellite and fiber
- Waveguides and microwave components
- Satellite link budgets; GEO vs LEO
- Fiber types, attenuation and dispersion, sources and detectors, WDM
Transmission lines and antennas
- Characteristic impedance, VSWR, reflection coefficient
- The Smith chart and impedance matching
- Antenna gain, beamwidth, polarization; propagation modes
A 6-week plan
| Week | Focus | Practice volume |
|---|---|---|
| 1 | Analog + digital communications | 80 problems |
| 2 | Networks + cellular | 60 problems |
| 3 | Microwave + satellite + fiber | 80 problems |
| 4 | Transmission lines + Smith chart + antennas | 70 problems |
| 5 | Computer systems + industrial electronics | 60 problems |
| 6 | Timed practice set + remediation | 1 set + 60 problems |
