用不同的方法来设计FIR数字滤波器,利用MATLAB来设计FIR数字滤波器.(Use different methods to design FIR digital filters, using MATLAB to design FIR digital filters.)

按照给定指标采用模拟低通滤波器（巴特沃思低通或者切比雪夫低通）去逼近理想模拟低通滤波器 ，然后通过双线性变换法对模拟滤波器进行数字化，得到数字滤波器 。(According to a given target analog low-pass filter (Butterworth or Chebyshev low-pass low-pass) to approximate the ideal analog low-pass filter, then through the bilinear transformation method to digitize the analog filters, digital filters has been .)

数字调制就是把数字基带信号的频谱搬移到高频处，形成适合在信道中传输的带通信号。基本的数字调制方式有振幅键控（ASK）、频移键控（FSK）、绝对相移键控（PSK）、相对（差分）相移键控（DPSK）。在接收端可以采用想干解调或非相干解调还原数字基带信号。 (Digital modulation is the spectrum shifting to high frequency digital baseband signals, suitable for the formation of bandpass signal transmission in the channel. Digital modulation basic amplitude keying (ASK), frequency shift keying (FSK), the absolute phase shift keying (PSK), relative (differential) phase shift keying (DPSK). At the receiving end can be used to dry the demodulation or non coherent demodulating the digital baseband signal. )
