One of the more challenging tasks facing test engineers is the creation of stimulus signals to exercise a PCB prototype or silicon turn, or to define complex high-frequency modulated signals for RF ...

In order to perform this harmonic reduction, a pure sine wave must first be applied to the Class-D amplifier system. Using the ternary modulated bitstreams described earlier, two pulse density ...

Fundamental to all wireless communications is modulation, the process of impressing the data to be transmitted on the radio carrier. Most wireless transmissions today are digital, and with the limited ...
