Time-domain Signal Measurement using Oscilloscope

Optoelectronic time-domain characterization of a 100 GHz sampling oscilloscope

We have performed an optoelectronic measurement of the impulse response of an ultrafast sampling oscilloscope with a nominal bandwidth of 100 GHz within a time window of approximately 100 ps. Our experimental technique also considers frequency components above the cut-off frequency of higher-order modes of the 1.0 mm coaxial line, which is shown to be important for the specification of the impu...

A Virtual Instrument Oscilloscope for signal measurements

In this paper, we discuss about the LabVIEW based graphical applications for the measurements of signal. A virtual instrument is designed in order to serve the purpose of oscilloscope with a user friendly interface at the front panel. The designed oscilloscope is derived from a hardware instrument named Digital Phosphor Oscilloscope TDS 5104B.Firstly the original hardware device functions are e...

Oscilloscope Testing by Means of Stochastic Signal

Using the time domain for analog signal representation

There is an ever-growing interest within the fields of neurophysiology—as well as within coding theory and signal processing—into the particular information transmission method employed by most neurons: spikes. Many models used today regard those voltage pulses as uniform events where only the occurrence of an event from a particular neuron at a particular moment in time matters. This signal re...

Time Domain Signal Analysis Using Wavelet Packet Decomposition Approach

This paper explains a study conducted based on wavelet packet transform techniques. In this paper the key idea underlying the construction of wavelet packet analysis (WPA) with various wavelet basis sets is elaborated. Since wavelet packet decomposition can provide more precise frequency resolution than wavelet decomposition the implementation of one dimensional wavelet packet transform and the...
