Which is better CWT or DWT?
CWT is a better pre-processing tool as it yields more accurate predictions than DWT.
Can digital signals have a range of values?
A digital signal is a signal that represents data as a sequence of discrete values. A digital signal can only take on one value from a finite set of possible values at a given time. With digital signals, the physical quantity representing the information can be many things: Variable electric current or voltage.
What can you do with digital signal processing?
DSP is used primarily in areas of audio signal, speech processing, RADAR, seismology, audio, SONAR, voice recognition, and some financial signals. For example, digital signal processing is used for speech compression for mobile phones, as well as speech transmission for mobile phones.
