Multiplying this output by the modulation signal and also with another reference signal, 90° out of phase, results in Equation 1.

We’ll review CW signal generation and characteristics, including phase-noise and signal synthesis using VCOs and phase-locked-loops. You will learn about analog and digital modulation generation ...

Since 2009 and 2010, when broadcasters had to switch to an HD signal, Cox and other providers have converted the digital signal into an analog signal. “We are one of the very last companies to ...

Overcoming conventional technological limitations to realize high-speed optical coherence modulation at 350 kHz. Structured light fields possess a wide range of unique and powerful characteristics. By ...

The ferro-TFET shows merits of reconfigurability, reduced footprint, and low supply voltage for signal modulation. This work provides the possibility for monolithic integration of both steep-slope ...

We report that back-propagating action potentials (bAPs) are not simply digital feedback signals in dendrites but also carry analogue information about the overall state of neurons. Analogue ...

Waveforms are shown in figure 4 and 5, and it’s worth flagging here that that’s another advantage of using GNU Radio software; the visualization of signals in real-time. Fig. 4: QPSK signal waveform ...

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 ...
