Nature is Analog Analog Electronics: An oldest and fundamental branch of electronics. Although much signal processing is being done digitally, it remains indispensable discipline. https://picasaweb.google.com/107263748601915715835/NesargiKarmicPranjal#5556691209155746434 First interface with ‘analog’ nature. All the natural phenomenon such as variation of light, temperature and in weather etc are defined in continuous time and value. Muhammad Amir Yousaf

Electronics reads Environment An electronic system normally (made to) interacts with nature. It reads the environmental phenomena and acts over it in the ordered fashion.

A Light Dependent Resistor Analog Signal Primary information from natural phenomena comes in the form of optical, acoustic, thermal or chemical etc signals. These signals are converted into electrical signals. The devices used for such conversions are called transducers or sensors. Signals from primary source of information are continuous in time so the electric signals obtained from the transducers. The electric signal is analogue of the primary information stream, it is therefore called ‘Analog Signal’ https://picasaweb.google.com/107263748601915715835/NesargiKarmicPranjal#5556691209155746434 A Light Dependent Resistor Muhammad Amir Yousaf

Signal Handling: An art Electronics is an art of handling information carrying electrical signals. The electrical signals obtained from the transducers could be very delicate and weak in strength and prone to noise and interference. Processing of electrical signals starts from this stage. It includes treatment of signal against the noise and decision making. After processing, the output signal converted back into the physical signal or quantities for display or actuation. https://picasaweb.google.com/107263748601915715835/NesargiKarmicPranjal#5556691209155746434 Muhammad Amir Yousaf

Signal Chain in an Electronic System A sensor converts the real-world signal into an analog electrical signal. This analog signal is often weak and noisy. Amplifiers are needed to strengthen the signal. A/D converters for digital processing if required. Muhammad Amir Yousaf

Typical Signal Chain in an Electronic System Analog filtering may be necessary to remove noise from the signal. This (is called) ‘front end’ processing (which) improves the signal-to-noise ratio (SNR). Most important building blocks used in the amplifier and filter stages is: Operational Amplifiers Signal-to-noise ratio (SNR) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise. It is defined as the ratio of signal power to the noise power. Muhammad Amir Yousaf

Signal Chain in an Electronic System An analog-to-digital converter transforms the analog signal into a stream of 0‘s and 1's. The digital data is processed by a CPU, such as a DSP, a microprocessor, or a microcontroller. Digital-to-analog conversion (DAC) is necessary to convert the stream of 0's and 1's back into analog form. Muhammad Amir Yousaf
