can anyone tell me please what does filter(chan,data) really works ie is it conv or what as i need inverse that operation in the reciever,
its urgent please
its urgent please
The "filter" function in Matlab is used to apply a digital filter to a set of data. It is commonly used to remove noise or unwanted frequencies from a signal, or to extract specific frequencies from a signal.
The "filter" function works by taking in two parameters: the channel (or filter) to be applied and the data to be filtered. It then performs a convolution between the data and the filter, which essentially multiplies and sums the two signals together. This process is repeated for each data point, resulting in a filtered output signal.
Yes, the "filter" function in Matlab allows you to design and apply your own custom filter. You can specify the filter coefficients and other parameters to create a filter that best suits your needs.
The "filter" function in Matlab can apply many different types of filters, including low-pass, high-pass, band-pass, and notch filters. It can also apply finite impulse response (FIR) and infinite impulse response (IIR) filters.
No, the "filter" function in Matlab can also be used for other types of data filtering, such as smoothing, denoising, and data interpolation. It is a versatile function that can be applied to a variety of data sets and applications.
