Arduino Analog Sampling – It’s All About Timing
Arduino analog sampling is a lot different than on an ordinary PC. 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
