This top-down feedback loop is the core of Predictive Coding [2]. The brain isn’t passively waiting for pixels from the optic nerve. It is a “hallucination machine” constantly generating a simulation of the world. When you look at a tree, your brain predicts what it’s going to see. It compares that top-down prediction with the bottom-up sensory data from your eyes. The brain doesn’t pass the whole image up the chain; it only passes up the prediction errors (the diffs). Your conscious experience is just your brain’s best guess of reality, corrected by sensory diffs.
A Pico board can however allow better control at lower frequencies within the typical AM radio station (~1000 KHz). While square waves are well-suited for frequency-modulating any PCM audio file (ignoring the unwanted harmonics), they cannot be used well for amplitude modulation. They can only encode ON or OFF instead of different audio amplitudes (think 1-bit envelope). Alright, no emitting arbitrary “.wav” files. We can at least emit a single audio frequency at a time using On-Off Keying. Let’s make some retro game sounds!

В условиях обострения геополитической ситуации в регионе спрос на ключевой драгметалл продолжит расти, полагает эксперт. С учетом общей экономической неопределенности золото останется главным «активовом-убежищем». В случае затягивания войны в Иране, не исключил Красноженов, котировки драгметалла могут достичь новых исторических максимумов.
