 # How to use FFT web
-FFT Web is an Out-Of-Tree block which sends a signal FFT by UDP to a websocket server. This websocket server packs and broadcast this FFT data to websockets, which can be opened by html/javascript code for real-time display of the fft in web-browsers (don't worry we are already providing that part ;) ).

 ## How to use FFT Web block
-FFT web is a FFT sink block you have to feed with the signal you want to analyse. for example you can put it just ater an USRP Source block to act as a spectrum analyser.
+FFT web is an FFT sink block you have to feed with the signal you want to analyze. For example you can put it just after a USRP Source block to act as a spectrum analyzer.
-FFT Web can be tune with several parameters :
+FFT Web can be tuned with several parameters :
 * **fft_size** The size of the FFT ( 256 is a good start)
 * **power max** The upper limit of the measured power in dB (-30 is a good start)
 * **power min** The lower limit of the measured power in dB (-100 is a good start)
-* **port** The port use to send the data. Usefull when you are using multiple fft web block. (default is 6663)
+* **port** The port used to send the data. Useful when you are using multiple FFT Web blocks. (default is 6663)
 * **frame rate** The frequency of the acquisition (10 is a good start)
-* **samp rate** This correspond to the bandwith of the signal
+* **samp rate** This corresponds to the bandwidth of the signal
 * **ip address** The address of the websocket server the data will be sent to. The address of our server is "srvwww.cortexlab.fr".
-The resolution of graphic will be ''samp rate/fft size''.
+The resolution of the graph will be ''samp rate/fft size''.
