A new technical paper titled “Three-to-one analog signal modulation with a single back-bias-controlled reconfigurable transistor” was published by researchers at NaMLab gGmbH, GlobalFoundries, and TU ...

In this section we introduce the tools necessary to evaluate and compare various analog voice modulation systems. In order to better understand the factors affecting speech intelligibility, we briefly ...

Testing can be one of the most problematic steps in a design chain. When new technologies emerge, test equipment usually lags a step behind. As such, it is imperative that test equipment become more ...

One popular way to reconstruct analog signals in microcontrollers (µCs) is through pulse width modulation (PWM). However, this modulation produces a large number of harmonic components, which limits ...

Modulation is the process of varying a higher frequency carrier wave to transmit information. Though it is theoretically possible to transmit baseband signals (or information) without modulating it, ...

Delta-sigma modulation is a cornerstone approach for high-resolution analogue-to-digital conversion, combining oversampling with active noise shaping to achieve superior signal fidelity. In these ...

Baseband modulation techniques encode information directly as the amplitude, width, or position of a pulse. They do not utilize a sinusoidal carrier. Some of these modulation schemes are known by the ...

Varying the voltage of a carrier or a direct current in order to transmit analog or digital data. Amplitude modulation (AM) is the oldest method of transmitting human voice electronically. In an ...
