The circuit of Figure 1 generates sinusoids down to very low frequencies with distortion in the region of 3% or less, yet has no feedback or gain-stabilizing components because none are needed. It ...
When we think about signals and systems, we often do so with an emphasis on creating and transmitting signals with specific characteristics. That is, we want the signal to have some desired amplitude, ...
Dana Puopolo’s Guest Commentary, “Let’s Keep AM Sounding Good” (Jan. 19) contains a number of technical errors. Mr. Puopolo’s thesis hinges on the ideas that the thing which causes 5 kHz low-pass ...
producing the frequency predicted by equation (8). Higher-order harmonics can be calculated similarly. As an example, Figure 1 shows the output spectrum for the quad-channel, 16-bit, 2.5 Gsps DAC38J84 ...
The ADL5561 and ADL5562 amplifiers simplify the driving of 12- to-16-bit analog-to-digital converters (ADCs) in advanced wire-line and wireless communications systems. These ultra-low-distortion ...
The integration of digital predistortion (DPD) within radio-over-fibre (RoF) architectures addresses the fundamental nonlinearity and memory impairments arising in optical and radio-frequency ...
