Modulation is the act of translating some low-frequency or baseband signal (voice, music, and data) to a higher frequency. Why do we modulate signals? There are at least two reasons: to allow the ...

Mechanical oscillators are present in almost every electronic device. They mainly consist of a resonating element providing an oscillating output with a specific frequency. Their ability to maintain a ...

One year after launching its flagship 63xx series of arbitrary waveform generators (AWGs), Spectrum Instrumentation now ...

Work on surface sensing in bacterial biofilms has focused on how cells transduce sensory input into cyclic diguanylate (c-di-GMP) signaling, low and high levels of which generally correlate with ...

What you need to know about understanding frequency response curves of loudspeakers. Note: Paul Dicomo was a great friend to eCoustics and many of us over the past 2 decades. Sadly, Paul lost a ...
