  • DSP engineers today write codes to implement a function on a DSP, architect hardware blocks and systems, and design algorithms. In this article, we take a look at the DSP scenario in India, career scope in this field and industry experts’ suggestions to aspiring engineers.
  • Digital signal processing (DSP) is the mathematical manipulation of an information signal to modify or improve it in some way. It is characterized by the representation of discrete time, discrete frequency, or other discrete domain signals by a sequence of numbers or symbols and the processing of these signals.
  • The goal of DSP is usually to measure, filter and/or compress continuous real-world analog signals. The first step is usually to convert the signal from an analog to a digital form, by sampling and then digitizing it using an analog-to-digital converter (ADC), which turns the analog signal into a stream of numbers. However, often, the required output signal is another analog output signal, which requires a digital-to-analog converter (DAC). Even if this process is more complex than analog processing and has a discrete value range, the application of computational power to digital signal processing allows for many advantages over analog processing in many applications, such as error detection and correction in transmission as well as data compression.

 


 

  • Designers who envision, plan, execute and inspire are the lifeline of an organisation. E4Y caught up with experts from various companies, who shared their views on career in analogue design in India. focuses on the scope, entry-level roles, skills required and industry experts’ suggestions.
  • An analogue signal uses some attribute of the medium to convey the signal's information. For example, an aneroid barometer uses the angular position of a needle as the signal to convey the information of changes in atmospheric pressure. Electrical signals may represent information by changing their voltage, current, frequency, or total charge. Information is converted from some other physical form (such as sound, light, temperature, pressure, position) to an electrical signal by a transducer which converts one type of energy into another (e.g. a microphone).
  • analogue circuit design requires more skills than digital systems design. An analogue circuit must be designed by hand, and the process is much less automated than digital systems.
  • A design engineer having strong understanding of analogue electronics and capable of handling analogue components, small signals and the sensor to the instrumentation will always sit in a high profile having scope to work in power, digital, RF and instrumentation
  • Skills to be developed - Having acquired the knowledge of discrete devices, op-amps would pose very little challenge in getting to know them. Be sure of which passive components you will use for what and be aware of their specific behaviour and functionalities.
