Information
- Our website is made by streamlit -python-.
- All graphs are implemeted using plotly.
Features
General Information
- Our website will give you multiple features to analyze your signals:
As our website is designed for :
- plotting your desired signals by determine signals frequency and amplitude.
- Add Multiple signals at the same time and show the final output signal.
- Upload signal from your files in csv formateand show it.
- Remove any signal you have added by selecting and deleting it.
- Add noise to your signal by determine signal to noise ratio(SNR) Which has a range if SNR=0 that means noise is extrem and if SNR=50 that means signal will appear without noise.
- sample your signal with 2 options:
By determine frequency you want in HZ OR By sampling with Max_frequency Scale (I wnant to sample with fmax,2fmax.....,10fmax)
- reconstruct your signal and this has more one option (you can't reconstrict it nicely if your sampling frecency <2fmax (according to nquist's law ), and you can reconstruct it well if sampling frequency >= 2fmax)
- Our website provide saving each graph of your signal as png and zooming in or out, also you can doenload your reconstructed signal in csv formate as well.

Adding 2 signal with different frequency
-There are many scenarios when sampling:
Sampling with frequency scale with sampling frequency < 2 fmax (Fmax=6.5 Hz as shown )
Sampling with frequency scale with sampling frequency = 2 fmax (Fmax=6.5 Hz as shown )
Samplind with frequency scale with sampling frequency > 2 fmax (Fmax=6.5 Hz as shown )
Sampling 2 signals (4hz&8hz) with sampling frequency=6hz
sampling with 2fmax with noise
sampling with Fmax scale
