The PA164/PA165 is high density power amplifier ICs that elevate the performance benchmarks and thermal management efficiency for single-chip power amplifiers. These devices are capable of providing 1A/4A of output current continuously, and up to 10A PEAK output for the PA165, while operating on voltage supplies of up to 200V. These ICs are designed to use separate supplies for the amplifier core and the output stage to help optimize overall power dissipation capabilities of up to 28W of internally generated heat.

Designed by MatrixTSL for use by students and professional engineers alike, E-blocks2 are small, rugged and modular circuit boards that can be connected together to form working electronic systems. Individual boards and bundles are currently available to support development using PIC® MCUs and Arduino® based hardware.

E-blocks2 is the latest generation of microcontroller boards from Matrix. There are currently 21 boards in the range with many more boards planned for release in early 2018. E-blocks2 boards give you a choice of programmer boards, with Arduino and PIC programmer boards already released and additional boards to be added in the New Year. The system then allows users to connect their choice from a range of boards, and build a complete system in a matter of minutes.

In the previous tutorial, various physical and data link layer protocols specified for computers and mobile devices were discussed. Continuing the subject of physical and data link protocols, in this tutorial, network access protocols specified for LPWAN will be discussed. 

LPWAN stands for Low Power Wide Area Network. In general, LPWAN is a low power long range wireless network in which battery powered IOT devices surrounded by wireless sensors (Wireless Sensor Network) are interconnected.

Audio Filters - Designing an Audio Mixer - 8/8

 MAX4468 Microphone Audio Pre Amplifier CircuitIn the previous tutorial, an audio equalizer was designed. In this tutorial, now an audio mixer will be designed. 
 
The Audio Mixer is an electronic device which combines and modifies the audio signals. The audio signals can be either in digital form or analog form. In digital form, the analog audio signals are encoded so that the audio information in the signal becomes independent of the amplitude of the signal.
 
Both analog and digital signals can be combined by different types of audio mixers. For mixing digital audio signals, digital signal processing techniques are used while for combining the analog audio signals, generally operational amplifiers are used.

Architecture of Bluetooth Low Energy (BLE) ProtocolIn the previous tutorial, reference architecture for IOT was compared with OSI and TCP-IP models and various data communication protocols for different layers of IOT architecture were mentioned. In this tutorial, the physical and data link layer protocols will be discussed in details. 

The physical and data link layer comprises of the IOT objects and physical networks connecting them with other objects or network. 

 

Part 3:IOT Standards and Protocols

 Comparison of OSI and TCP-IP Model LayersIn the previous tutorial, a basic architecture of an IOT system was discussed. From the discussions in the previous tutorial, it must be clear that communication network is the backbone of any IOT system. It is only the (internet) network that enables IOT devices (boards) and cloud based services and applications to communicate with each other. Without internet network, IOT is nothing. Data communication on an internet network is not as straight forward. There are myriad of heterogeneous devices connected over internet and these plethora of unique devices need to communicate in a secure, reliable and routed fashion.

IOT Communication through GatewayIn the previous tutorial, a brief introduction of Internet of things was presented. The importance, challenges, applications and trends in IOT were discussed. Now, equipped with basic understanding of IOT, it's time to investigate the building blocks of IOT. IOT is developed as a package with integration of various technologies.
 
Each technology has its own principle role within the IOT system. In this tutorial, the basic building blocks of IOT and their place in an IOT infrastructure will be examined. 

Audio Filters - Designing an Audio Equalizer-7/8

3-Band Audio Equalizer Circuit In the previous tutorial, an audio crossover was designed using high pass and low pass audio filter. In this tutorial, an audio equalizer will be designed. An Equalizer (abbreviated as EQ) is an audio equipment which cut or boosts the certain frequency components from the audio signal. This process of adjusting the frequency components is called as Equalization.
The equalizers are widely used in the audio systems during recording of sound as well as in amplifiers and mixers. As they are used in the audio system so are called Audio Equalizer. 

Audio Filters - Designing a 2-Way Audio Crossover - 6/8

2-Way Audio Crossover Circuit In the previous tutorial, fundamentals of audio filters were discussed. The audio filters can be passive or active depending upon the use of passive or active components in their designing. On the basis of frequency response, filters can be classified as high pass, low pass, band pass, Notch, band reject, T-Notch, all pass and equalizer filters. In this tutorial, an audio crossover will be designed. 
 
The Audio crossover is an electronics circuit which splits the audio signal into two or more frequency bands. These frequency bands are then, sent to the different audio drivers (Twitters, Mid Range and Woofers). A single speaker is not capable to serve the whole range of audible frequencies due to the limitations of its construction. So, different drivers (speakers) are required to deliver different range of audio frequencies.
