Arduino Morse Decoder – How It Works
Let’s examine how an Arduino Morse Decoder works, and look at some popular solutions available. Read more
Signal Analysis for a Morse Decoder
Audio signals exist in the time domain. Sound is a complex mixture of waves at different frequencies. These waves vary in shape and strength. Traditionally, engineers consider audio as a whole bunch of sinusoidal tones mixed together. You can visualize this complex waveform on an oscilloscope. Read more
