“…Advances in solutions that address digital formation have led to the development of complementary metal-oxide-semiconductor (CMOS) technology sampling prototypes [7][8][9][10][11][12]. Emerging attempts to address optimization of dynamic range resolution have led to the development of a modulo analog-to-digital converter [13].…”

“…It is important to note that the reproduced signal is limited to 256 samples, this is to ease the processing pressure on Excel. The new odd/even order sampling mathematical model in Equations (12) and (13) was applied after Fourier Transform Analysis was applied to obtain the sample frequency behavior shown in Figure 6. Results in Figure 6 validate the research assumption that the new odd/even order sampling was half the sampling frequency.…”

“…Axi bus access is primary self-controlled but state transitions such as write, read, and enable are externally controlled by Process Controllers. The derived Equations (12) and (13) are implemented onto a DSP and signal data is loaded through the axi bus from Block-RAM. Different signal source data selection, a switch between odd or even order through memory strobe, and any other interesting application procedure is software programmed through a Scalar Processing sub block.…”

Digitization is at the center of fourth industrial revolution (4IR) with previously analog systems being digitized through an analog-to-digital converter. In addition, 4IR applications such as fifth generation (5G) Cellular Networks Technology and Cognitive Electronic Warfare (EW) at some point interface digitally through an analog-to-digital converter. Efficient use of digital resources such as memory, largely depends on the signal sampling design of analog-to-digital converters. Existing even order sampling has been found to perform better than traditional sampling techniques. Research on the efficiency of a digital interface with a 4IR platform is still in its infancy. This paper presents a performance study of three sampling techniques: the proposed new and novel odd/even order sampling architecture, existing Mod-∆, and traditional 1st order delta-sigma, to address this. Step-size signal-to-noise (SNR), dynamic range, and sampling frequency are also studied. It was found that the proposed new and novel odd/even order sampling achieved an SNR performance of 6 dB in comparison to 18 dB for Mod-∆. Sampling frequency findings indicated that the proposed new and novel odd/even order sampling achieved a sampling frequency of 2 kHz in comparison to 8 kHz from a traditional 1st order sigma-delta. Dynamic range findings indicated that the proposed odd/even order sampling has achieved a dynamic range of 1.088 volts/ms in comparison to 1.185 volts/ms from a traditional 1st order sigma-delta. Findings have indicated that the proposed odd/even order sampling has superior SNR and sampling frequency performances, while the dynamic range is reduced by 8%.
