Description: This package contains script to calculate aliasing for given time domain signal. Script to plot in time domain the function: x(t)=A0cos(2pif0t)+A1cos(2pif1t)
where fs1=300 Hz and fs2=150 Hz (sampling rate)
A0 and A1 are amplitude s signal (armónicos).
f0 is the maximun component in frecuency of the signal to sample,
when it shows X(t) signal with a sampling frecuency 300 Hz,
we will see Aliasing :)
It s because we aren t meetting with the Nyquist Theorem, because we don t choice Fs>=2FNy Fs(Sampling Frec) FNy(Frec Nyquist) to sample aplying fft(fast fourier transform) with at least 600 Hz.

Description: 实验一
一、观察采样引起的混叠。（来源：p57 习题1-3）
设模拟信号为 ，t的单位为毫秒(ms)。
1. 设采样频率为3kHz，确定与 混叠的采样重建信号 。
2. 画出 和 在 范围内的连续波形。（因数字计算机无法真正画出连续波形，可用较密的离散点的连线来近似。）
3. 分别用 和 在两信号波形上标记出3kHz采样点。
两信号波形是否相同？采样后的两序列是否相同？
-11 experiments to observe the sampling due to aliasing. (Source: p57 Problem 1-3), based analog signal, t' s in milliseconds (ms). 1. Based sampling frequency of 3kHz, sample identification and reconstruction of signal aliasing. 2. Draw and the continuous wave within the scope. (Because digital computers can not really draw a continuous waveform, can be more dense, discrete points to approximate the connection.) 3. Respectively and the two signal waveforms 3kHz sampling points on the mark. Two waveforms is the same? Sample after the two sequences are the same?

Description: BACKPROJ uses the filtered or unfiltered backprojection algorithm to perform the inverse Radon transform. The filter is designed directly in the frequency domain and then multiplied by the FFT of the projections. The projections are zero-padded to a power of 2 before filtering to prevent spatial domain aliasing and to speed up the FFT.-BACKPROJ uses the filtered or unfiltered backprojection algorithm to perform the inverse Radon transform.
