Abstract:

The quality of the signal is essential in digital communication and signal processing. The transmission channel is also important. Modulation is used for effectively transmission of signal. There exist several types of modulation techniques. One of such is the pulse code modulation (PCM). The performance of PCM is however affected by quantization error and noise in the transmission channel, which affects the quality of the output. Against this backdrop, this paper presents the use of differential pulse code modulation (DPCM) so as to address the limitation of pulse code modulation. The simulat

Abstract:

<p>In this paper, we have developed a hardware-based model of pulse code modulation (PCM) system for voice frequencies. Firstly, we have constructed sample and hold circuit using triggered semiconductor switch (e.g., MOSFET), which is capable of sampling voice signals at 8 kHz according to Nyquist theory. Then an Analogue to Digital Converter (ADC) Integrated Circuit (IC) is introduced to quantize and to digitize of the output of the sample and hold as pulse amplitude modulation (PAM). The converted outputs are 8-bit digital parallel value per sample at a frequency of 8 kHz. Finally, a p

Abstract:

In power communication systems, the pulse code modulation (PCM) equipment play an important role. Its security has been a focus of attention, when the concept of cyber physical system is proposed. In order to solve the security problem of PCM equipments, a Bayesian Network (BN) model is used in this paper. By analyzing the sensitivity of BN model, we can get the influence of each input variable to outcome variables. For illustration, four PCM equipments are selected from some substations. They are utilized to show the feasibility of the BN model in evaluating the security of PCM equipments and

Abstract:

Abstract Recent implementations of Sigma-Delta (ΣΔ) converters have achieved low cost, low power consumption, and high integration while maintaining resolution as high as in Nyquist-rate converters. However, its usage implies demodulating the source signal delivered from ΣΔ modulation to Pulse-Code Modulation (PCM) on a pre-processing stage. This work proposes an algorithm based on Discrete Cosine Transform for impulsive signal detection to be applied directly on a modulated ΣΔ bitstream, targeting to reduce computational cost in acoustic event detection applications such as gunshot recognitio

Abstract:

M-ary pulse-amplitude modulation (PAM) meets the requirements of data center communication because of its simplicity, but coarse entropy granularity cannot meet the dynamic bandwidth demands, and there is a large capacity gap between uniform formats and the Shannon limit. The dense wavelength division multiplexing (DWDM) system is widely used to increase the channel capacity, but low spectral efficiency of the intensity modulation/direct detection (IM/DD) solution restricts the throughput of the modern DWDM data center networks. Probabilistic shaping distribution is a good candidate to offer u

Abstract:

The aim of this paper is to design, analyze and compare four different systems for ADC (analog-to-digital conversion) of vibration signals. Measurement of vibration signals is of particular importance in many areas, such as predictive maintenance or structural health monitoring. Wireless systems for vibration measurements becomes very topical, due to much easier and cheaper installation compared to wired systems. Due to the lack of transmission bandwidth and energy in wireless measurement systems, the amount of digital data being sent has to be reduced; hence, we have to apply ADC systems that
