Analog to Digital Converter (ADC)


https://www.electronics-lab.com/article/analog-to-digital-converter-adc/

Analog to Digital Converter An analog-to-digital converter (ADC) is an electronic circuit that is used to convert a real-world signal into a digital or binary code. Real-world signals are usually taken from a sensory system which are generally analog in nature and represent instantaneous value of the measured entity. The sensory system may represent any […]

Analog To Digital Conversion – Performance Criteria


https://www.electronics-lab.com/article/analog-to-digital-conversion-performance-criteria/

Overview In this series of articles, we considered PCM (Pulse Code Modulation) as a method of digital representation of an analog signal. In the PCM method, the samples of the continuous wave are allowed to take only certain discrete values. These amplitudes are then assigned a code, where each code uniquely represents the magnitude of […]

Analog To Digital Conversion – Practical Considerations


https://www.electronics-lab.com/article/analog-to-digital-conversion-practical-considerations/

In the previous articles about A/D conversion, we considered the concepts of ‘sampling’, ‘quantization’, and ‘binary encoding’ as building blocks of a PCM system. Now, we review those concepts from a practical perspective. To perform the analog-to-digital conversion, the first stage is ‘sampling’. There are different regular sampling methods: Ideal Sampling: In ideal Sampling, the […]

Analog To Digital Conversion – Binary Encoding


https://www.electronics-lab.com/article/analog-to-digital-conversion-part-2/

Introduction In the first part of this article, we considered the two main stages of a PCM (Pulse Code Modulation) system as the widespread A/D (Analog to Digital Conversion) method and we saw how a continuous signal can be sampled in time and then quantized to limited integer levels in amplitude. The quantum levels are […]

Binary Numbers


https://www.electronics-lab.com/article/binary-numbers/

Binary Numbers The binary numbers are expressed in the base-2 number system which has only two (2) distinct number values i.e. 0 and 1. Just like, most common, decimal numbers are expressed in a base-10 number system having ten (10) distinct numbers from 0 to 9. These number systems are designed to express information and […]

Add PlainDAQ Carrier Board to Raspberry Pi Pico for Analog Functionality


https://www.electronics-lab.com/add-plaindaq-carrier-board-to-raspberry-pi-pico-for-analog-functionality/

We have already come across tens if not hundreds of Raspberry Pi’s in-house silicon tapeout RP2040 integrated boards. The RP2040 was first seen in Raspberry Pi’s own microcontroller board– RPi Pico that features a dual-core Arm Cortex-M0+ processor with 264KB internal RAM and support for up to 16MB of off-chip flash storage. To add analog […]
