How an IR remote control works, explained from real oscilloscope measurements: carrier, MARK, SPACE, header, bit timing and NEC identification.
GX-TXT-v3 DC bias measurements, current consumption and NE555 timer verification compared with LTspice simulation.
High-resolution audio goes beyond the CD standard, offering sample rates of up to 192 kHz and 24-bit depth. While some listeners praise its greater naturalness and detail, others question the practical value of frequencies above 20 kHz. Scientific studies and psychoacoustic tests have produced conflicting results, fueling an ongoing debate over perceived quality, the limits of human hearing, and possible technical distortions.
