Signal Integrity Tips

Ever wondered why an NRZ spectrum has no energy at the bit rate? The nulls at the bit rate (and integer multiples of the bit rate) are explained in this 8 minute video tutorial, which compares the spectrum of a square wave and NRZ data. As a bonus we’ll see how the rise and fall [...]

James Clerk Maxwell at University of Cambridge with one of his colour wheels James Clerk Maxwell was born June 13th, 1831 in Edinburgh, Scotland, UK. He synthesized previously unrelated observations, experiments, and equations of electricity, magnetism, and optics into a consistent theory and set of equations—Maxwell’s equations—demonstrating that electricity, magnetism and even light are all manifestations [...]

We’ve been wondering for years what the secret of signal integrity is. Now we have the answer from Monster Cable and their iCable for iPhone and iPod: 24k gold-plated contacts for greater signal integrity Nice looking Y-cable (RCA pair to 3.5mm stereo jack). I can see how it would works at audio frequencies, but I wonder how [...]
