How a pure sine wave inverter works circuit diagrams?
Filter the output with a low-pass filter whose cut-off frequency is less than 120 Hz. That process removes the energy at harmonic frequencies from the output waveform, leaving only the energy at 60 Hz.
Difference between fourier series and z-transform?
Laplace = analogue signal Fourier = digital signal Notes on comparisons between Fourier and Laplace transforms: The Laplace transform of a function is just like the Fourier transform of the same function, except for two things. The term in the exponential of a Laplace transform is a complex number instead of just an imaginary number and the lower limit of integration doesn't need to start at -∞. The exponential factor has the effect of forcing the signals to converge. That is why the Laplace transform can be applied to a broader class of signals than the Fourier transform, including exponentially growing signals. In a Fourier transform, both the signal in time domain and its spectrum in frequency domain are a one-dimensional, complex function. However, the Laplace transform of the 1D signal is a complex function defined over a two-dimensional complex plane, called the s-plane, spanned by two variables, one for the horizontal real axis and one for the vertical imaginary axis. If this 2D function is evaluated along the imaginary axis, the Laplace transform simply becomes the Fourier transform.
Why low pass filters are required in demodulation process?
Demodulation takes place to extract the low-frequency signal from the high-frequency carrier, using a nonlinear process that produces components at the signal frequency. The LP filter is used to eliminate the high-frequency carrier component from the signal so that it does not cause problems at a later stage in the amplification of the signal.
Tell you what an intermediate frequency amplifier do?
The intermediate frequency (IF) amplifier lies between the mixer and the demodulator. The mixer shifts the input radio frequency (RF) signal into the range of the IF amplifier. The IF amplifer is a band pass amplifier, so only RF signals that are the IF frequency distance away from the local oscillator in the mixer can pass through to the demodulator. This process is called the superhetrodyne process.
What is the difference between time division multiplexing and space division multiplexing?
The difference is the way the data is separated and transmitted between two points. In Space Division the data is separated physically i.e. the carrier medium is divided into different channels. This could be by using different wires, waveguides, optical cables, etc, or by frequency i.e. radio channel, carrier frequency. Time Division uses the same channel in one of the above but different data is given a specific order and location in time for transmission. e.g. Synchronsation followed by type (a) data, then type (b) data followed by a checksum. The whole process is repeated continuously until transfer is complete.
What analyzes an objects spectrum?
A spectrum analyzer or spectral analyzer is a device used to examine the spectral composition of some electrical, acoustic, or optical waveform. It may also measure the power spectrum. There are analog and digital spectrum analyzers: * An analog spectrum analyzer uses either a variable band-pass filter whose mid-frequency is automatically tuned (shifted, swept) through the range of frequencies of which the spectrum is to be measured or a superheterodyne receiver where the local oscillator is swept through a range of frequencies. * A digitalspectrum analyzer computes the discrete Fourier transform (DFT), a mathematical process that transforms a waveform into the components of its frequency spectrum. http://en.wikipedia.org/wiki/Spectrum_analyzer
What are the uses of spectrum analyzer?

What is sound analysis?
Sound analysis is the process of examining and interpreting audio signals to extract meaningful information about the sound. It involves techniques such as waveform analysis, frequency spectrum analysis, and time-frequency analysis to understand the characteristics of the sound, such as pitch, intensity, and timbre. Sound analysis is commonly used in fields such as music, speech recognition, and environmental noise monitoring.

What is modal vibration and spectral vibration?
An individual mode is a particular frequency and phase (direction) of vibration. Spectral vibration is were you take a particular vibration time-wave form and view its individual frequency components using a process called fast fourier transform (FFT). Individual frequency components can be assessed using software packages such as System1, VibroNurse, Prism4, Machine Analyst to assess machinery/structural conditions.
