To modify the design is also very difficult to achieve
To modify the design is also very difficult to achieve. For example, if you later find that you need a higher order filters, it is necessary to change the hardware to achieve new design. Digital filter software, laptop battery does not have this problem, and to provide a flexible platform that can achieve a variety of applications in a single hardware.If these limitations is unable to meet the requirements of the project specification, then you need a new stand-alone instrument, it would greatly increase the cost of the final system.Dolph - cut than Chebyshev window and corrugated FIR design method.
In addition to the virtual instruments and digital signal processing have played a virtual instrument through the use of graphical programming development environment NI LabVIEW software platform based on the advantages, ease-of-use advantages of further development, it allows more people to participate in software development and equipment designs. LabVIEW not only provides a completely traditional text-based programming language, graphical programming, the programming process more intuitive and convenient, Notebook battery saves a lot of time need to be familiar with the programming environment and required by the grammar.
Software-based solutions for DSP engineers, using traditional tools very painful. Typical development process from the beginning of the algorithm design, it needs to use a variety of mathematical modeling environment, which requires enough familiarity with a text-based commands and syntax. After the completion of the algorithm, the realization of embedded systems has brought new difficulties. Embedded system design is the concept of real-time processing, on-board memory availability as well as text-based programming language and syntax required to have in-depth knowledge in software development.
