WebApr 22, 2024 · Yes, you are right. By downsampling we are reducing sample points per second (basically lowering the sampling rate). The time gap between adjacent samples increases as a result, hence degrading the resolution in time. Imagine, your original sampling frequency was $\text{100kHz}$.

WebA multirate filter is a cascade combining upsampling, downsampling, and convolution filters (FIR or IIR). Such filter structures are often used to implement resampling systems, wherein the output is a resampled version of the input at a different rate. Informally, for an input u ( n), the output of a resampling system is y ( k) = u ( S ⋅ k - D). WebDescription. example. y = downsample (x,n) decreases the sample rate of x by keeping the first sample and then every n th sample after the first. If x is a matrix, the function treats each column as a separate sequence. y = downsample (x,n,phase) specifies the number of samples by which to offset the downsampled sequence.
