Please translate the following passage into Chinese

Digital signal processing and analog signal processing are subfields of signal processing. DSP applications include

audio and speech signal processing, sonar and radar signal processing, sensor array processing, spectral estimation,

statistical

signal

processing,

digital

image

processing,

signal

processing

for

communications,

control

of

systems,

biomedical

signal

processing,

seismic

data

processing,

among

others.

DSP

algorithms

have

long

been

run

on

standard

computers,

as

well

as

on

specialized

processors

called

digital

signal

processors,

and

on

purpose- built

hardware such as application- specific integrated circuit (ASICs). Currently, there are additional technologies used

for

digital

signal

processing

including

more

powerful

general

purpose

microprocessors,

field-programmable

gate

arrays

(FPGAs),

digital

signal

controllers

(mostly

for

industrial

applications

such

as

motor

control),

and

stream

processors, among others.

2.

Please describe Sampling Theorem.

3.

Please give the calculation steps of FFT-based fast linear convolution algorithm.
