This visualization displays the single-sided frequency spectrum of a tremor analysis, plotting raw magnitude against frequency in Hertz. The code loads heart rate data from an external package, applies a radix-4 Fast Fourier Transform via a custom FFT class, and computes magnitude values from the resulting complex array. Using D3.js with `scaleLinear` and a `line` generator, the chart renders on an SVG canvas with labeled axes and a gray interior rectangle. The y-axis shows raw magnitude, while the x-axis spans from zero to the Nyquist frequency.

single sided magnitude spectrum tremor analysis

This visualization displays the single-sided magnitude spectrum of a tremor analysis signal, plotting frequency in Hertz against magnitude in decibels. The chart uses a logarithmic x-axis scale to show the frequency distribution of heart rate data sampled at 62.5 Hz. The code calculates a Fast Fourier Transform using a custom FFT class and visualizes the resulting magnitudes with D3.js, including axes and a line path. The visualization uses a custom `viz` function that applies log and linear scaling to map data points.

FFT of tremor analysis single sided

This visualization displays the single-sided magnitude spectrum of a tremor analysis signal, plotting frequency bins against raw FFT magnitude values. The code processes 512 heart rate data points through a custom FFT class, calculates magnitude from the complex output, and renders the results as a line chart using D3.js scales and path generators. The interactive resizing is handled through the `@drbagwell/responsive-viz-axes` library, while the visualization itself uses `d3.scaleLinear`, `d3.line`, and `d3.extent` to map the transformed frequency data across the SVG canvas.

FFT of tremor analysis

This example displays the double-sided magnitude spectrum of a tremor analysis, plotting frequency in Hertz against raw magnitude as a connected line chart. The code processes 512 heart rate data points through a custom FFT implementation, then visualizes the resulting complex spectrum using d3.js scales, axes, and a line generator. The visualization updates responsively with the container size, using a gray inner plot area with labeled axes.

shiftFFT of tremor analysis

This example visualizes a Fast Fourier Transform (FFT) of tremor analysis data, displaying the double-sided magnitude spectrum of heart rate samples. The x-axis shows frequency in Hertz, while the y-axis displays raw magnitude values. The visualization uses a standard line chart rendered with d3.select and d3.line, with axes generated by @drbagwell/responsive-viz-axes. The data is processed through a custom radix-4 FFT implementation in fftClass.js, which computes the transform and completes the spectrum before plotting magnitude values against frequency.

tremor analysis Magnitude (dB)

This visualization displays the frequency spectrum of tremor heart-rate data, plotting magnitude in decibels against frequency on logarithmic scales. The heart-rate signal (512 samples) is processed through a custom radix-4 Fast Fourier Transform (FFT) implementation (fftClass.js), producing a double-sided spectrum from which magnitude values are calculated. The resulting frequency-magnitude pairs are rendered as a line chart using D3.js, with the viz.js module handling logarithmic scaling, axes, and the SVG line path. The plot reveals dominant frequency components in the tremor data, with a gray background rectangle framing the chart area.

FFT-tremor-analysis-hz

This visualization displays a single-sided magnitude spectrum of heart rate tremor data, showing frequency components on the x-axis against raw magnitude on the y-axis. It applies a radix-4 FFT implementation from a custom `FFT` class to 512 samples of heart rate data, then plots the computed magnitudes as a line chart. The visualization uses D3.js scales, line generator, and responsive axes from `@drbagwell/responsive-viz-axes`, with the frequency axis calibrated using a sampling rate of 62.5 Hz.

Amplitude FFT-tremor-analysis-hz

This visualization displays the frequency spectrum of heart rate data from a tremor analysis dataset, plotting raw magnitude against frequency in Hertz. The code uses a custom FFT class to transform 512 samples of heart rate data, then applies an excludeDCandNyquist function to remove DC and Nyquist components. The resulting frequency-domain representation is rendered as a line chart using D3.js, with axes drawn via the responsive-viz-axes library. The x-axis shows frequencies from 0 to the Nyquist frequency (31.25 Hz), while the y-axis displays the computed magnitude values, revealing the dominant frequency components in the tremor signal.

shiftFFT-tremor-analysis-hz

This visualization displays a tremor analysis by plotting the frequency spectrum of heart rate data sampled at 62.5 Hz. It shows a line chart of raw magnitude versus frequency in Hertz, with the DC and Nyquist components excluded and the spectrum shifted to center around zero frequency. The code implements a custom FFT class using a radix-4 algorithm to transform 512 data points, then calculates magnitude and phase arrays. It uses D3 for rendering with `scaleLinear`, `line`, and `extent`, alongside responsive axes from `@drbagwell/responsive-viz-axes`.
