Similarly, the treatment of photodetectors—specifically PIN diodes and Avalanche Photodiodes (APDs)—is notable for its depth. Gowar navigates the trade-offs between sensitivity and noise, providing the necessary background to understand modern receiver design. The digital search for the "Gowar PDF" often spikes during exam periods precisely because his explanations of receiver sensitivity and signal-to-noise ratio (SNR) calculations are among the clearest available in the literature. optical communication systems john gowar pdf
