    abundant structure information of a molecule. Most molecules are infrared active except for several homonuclear diatomic molecules such as O2‚ N2 and Cl2 due to the zero dipole change in the vibration and rotation of these molecules Concept: Fourier transform spectroscopy is a less intuitive way to obtain the same information. Rather than shining a monochromatic beam of light at the sample‚ this technique shines a beam containing many frequencies of light at once‚ and measures how much of that beam

    of the concepts presented‚ virtual test instrumentation is used. Laptop computers play an essential role during the class to provide actual "hands on" lab experience. The labs demonstrate the principles of sampling‚ Fourier series‚ sinusoidal waveforms‚ FFT/DFT/Inverse Fourier transforms‚ signal generation and other mixed signal testing concepts. Each student receives a personal copy of the DSP Lab software‚ which can be kept for later use and a 300+ page reference manual titled "Fundamentals of Mixed

    advancements in multimedia computing and high speed wired and wireless communications made DSP to grab increased attention. For an N-point transformation the direct computation of the Discrete Fourier Transform (DFT) requires N2 operations. Cooley and Turkey explained the concept of Fast Fourier Transform (FFT) which reduces the order of computation to Nlog2N. The FFT is not an approximation of the DFT‚ it’s exactly equal to the DFT. FFT decomposes the set of data to be transformed into a series

    fluctuations in the wire that connects an mp3 player to a loudspeaker )‚ can be represented in Discrete Fourier Transform(DFT)‚ as a combination of pure frequencies. It’s universal in signal processing as well as can be used for applications such as the compression of images and audio files. The DFT is so prevalent due to the FFT algorithm which makes it possible to calculate Fourier transforms dynamically. Even then efforts to improve the calculation of DFT have a long and generally overlooked history

    SMART ENERGY METER A smart meter is usually an electrical meter that records consumption of electric energy in intervals of an hour or less and communicates that information at least daily back to the utility for monitoring and billing purposes. Smart meters enable two-way communication between the meter and the central system. Unlike home energy monitors‚ smart meters can gather data for remote reporting. Smart Meters" usually involve real-time or near real-time sensors‚ power outage notification

Further‚ it introduces Z-transform and its inverse and followed by their applications to the analysis of LTI systems. A framework for designing analog and digital filters (both FIR and IIR) is introduced starting with mapping of filter specifications from continuous Laplace transformation to Z-transform‚ structure realization based on Direct‚ Cascade‚ and Parallel forms‚ analysis of finite precision effects‚ and
