The average textbook definition of modulation reads: modulation is a process in which the frequency, phase or amplitude of a carrier wave varies in step with the instantaneous value of the modulating ...

A domestic research team has developed a technology that can control light at a speed thousands of times faster than existing technologies. Dr. Shin Hee-jun of the Pohang Accelerator Laboratory and ...

Strike a bell, and the bell rings at its resonance modes. Strike it harder and the bell rings at the same tone, only louder. Now imagine a small crack in the bell, perhaps invisible to the eye. We ...

Pulse Width Modulation (PWM) or Pulse Duration Modulation (PDM) is a technique of converting analog signals into rectangular waveforms. The width of the waveform varies in proportion with the ...

An arbitrary waveform generator (AWG) is a powerful and flexible signal source capable of generating any wave shape within the bandwidth and amplitude range of the generator. Populating an AWG with ...

When characterizing jitter performance, it is common to measure jitter output of a transmitter and jitter tolerance of a receiver. When measuring jitter tolerance, various quantities of intersymbol ...
