A speech signal filterbank, using melscale frequency and framebanking.( 1. For speech signal can be represented as a discrete sequence of frames (or feature vectors) that can be used as the input to a speech recogniser. Important ideas and techniques that are used in the assignment are the design of a (Mel frequency scale) audio filterbank, , windowing of a continuous audio signal, spectrum analysis of the signal, filtering as multiplication in the frequency domain, the visual representation of a speech signal as a spectrogram, appreciation of the acoustic variability in real speech utterances. 2. To gain a deeper knowledge of the application of MATLAB programming to audio signal processing. 3. To gain practice in the art of writing a formal report: structure, content, style, use of diagrams, presentation etc. etc. )

In this paper, we consider the use of Modulation Spectra for voice pathology detection and classification. To reduce the high-dimensionality space generated by Modulation spectra

二相相移键控（BPSK）调制解调过程的MATLAB仿真实现。ASK、FSK、PSK这三种数字调制方式在抗干扰噪声能力和信号频谱利用率等方面，以相干PSK的性能最好，目前已在中、高速传输数据时得到广泛应用。(Binary phase shift keying (BPSK) modulation and demodulation process, MATLAB Simulation. ASK, FSK, PSK modulation in the three digital noise interference and signal spectrum efficiency, etc., to the best performance of coherent PSK, is now in the middle and high-speed transmission data are widely used.)

Induction machines are more rugged, compact, cheap and reliable in comparison to other machines used in similar applications. Vector controlled induction motor drive outperforms the dc motor drive because of higher transient current capability, increased speed range and lower rotor inertia

一种（LFM）Linear frequency modulation雷达的仿真(Linear frequency modulation (LFM) radar simulation)

本代码设计的切比雪夫1型滤波器，与MATLAB中的切比雪夫滤波器不同的是输出为未归一化的零极点，输入只要是通带频率，通带波动，截止频率，阻带衰减即可，更便于抄做(The code design of Chebyshev Type 1 filter, and MATLAB in the Chebyshev filter output is not different is that the poles and zeros of the normalized input as long as the pass-band frequency, pass-band fluctuations, cutoff frequency, stopband attenuation can be more easily copied to do)
