A typical microprocessor system works by having a CPU send an address to the memory subsystem along with either a read request or a write request containing a piece of data to be written. Various other devices in the system will look at the addresses sent out from the CPU, decide whether they are "interesting", and react accordingly. is hurricane capitalized when named

L'aliasing può verificarsi sia nel tempo (aliasing temporale) sia nello spazio (aliasing spaziale).

It’s not very desirable. If your cutoff frequency is 1/2 your sample rate, that means signals at 20 Hz will be attenuated by 3dB, and the rolloff rate beyond that depends on the order of the filter you use.
