ヒストグラムの時間変化グラフの出力
이전 댓글 표시
1秒間でN=1000点の値を時系列で記録した電圧信号があると仮定した場合、 x軸は時間、y軸は電圧、z軸は1秒間の信号を0.1秒毎に10分割したヒストグラムの度数を色で、 平面に表現する方法はありませんか?
以下が元信号です。
Fs = 1/1000 ; % サンプリング周波数
t = (0:1:999) * Fs; % 時間軸
y = sin(2*pi*1*t); % 信号
使っているversionは以下です。

Approximate translation:
Assuming that there is a voltage signal recorded in time series of N = 1000 points in one second, the x axis is time, the y axis is voltage, and the z axis is histogram obtained by dividing the signal of 1 second every 10 seconds Is there a way to express the frequency of the frequency on a plane in color?
The following is the original signal.
Fs = 1/1000;% sampling frequency
T = (0: 1: 999) * Fs;% Time axis
Y = sin (2 * pi * 1 * t);% signal
The version you are using is below.
