Description: Description
Scientific calculator. Allows to perform caclulation with high precicion and implements most populatr mathematical functions: sin, cos, tan, asin, acon, atan, exp, log, sqr, floor and ceil. Also it make it possible to define your own function, store results in variables and use variable sin expressions. Calculator store al formuls you have entered. Plot function can be used to draw graph of function with single argument.
More detailed description of calculator is here.

Notes
* Write formula using normal infix notation, for example (x^2+ y^2)/1.5. To execute statement use Evaluate command.
* Use variable to write generic formulas, by changing values assigned to the variables you wil be able to repeat calculation for all input data with minimal typing. Define your own functions which also can speedup your work and reduce probability of making an error.
* It is possible to write small functional programs using conditional ?: operator. For example sum of arithmetic progression can be calculated by the following function
sum(x)=x>0?x+sum(x-1):0
Calculator has only < and > comparison operators (because comparing floating point number for equality is any case bad idea). But it is also to check that value belongs to specified range using min<x>max operator.
* All statement you have entered and stored in database. You can select proper statement using List command. Statements are marked with three differen

Description: 脉冲编码调制(PCM)实现
编程实现PCM技术的三个过程：采样、量化与编码。
采样：低通连续信号采样，以 x=sin(200*t) m=x./(200*t) m=m.*m 为例说明低通采样定理，绘出信号时、频图形；带通连续信号采样，以x=sin(20*t) m=x./t 为例说明带通采样定理，绘出信号时、频图形。
量化：均匀量化，以幅度 的正弦信号为例实现为64级电平的均匀量化；非均匀量化，输入A律PCM编码器的正弦信号 ，采样序列为 ，将其进行PCM编码，给出编码器的输出码组序列
编码：以上述信号为例，实现A律的13折线近似法及国际标准PCM对数A律量化编码。-Pulse code modulation (PCM) to achieve
PCM technology programming three processes: sampling, quantization and coding.
Sample: low-pass continuous signal sampling to x = sin (200* t) m = x./(200* t) m = m.* m an example low-pass sampling theorem, draw the signal, frequency graphics bandpass sampling continuous signals to x = sin (20* t) m = x./t an example bandpass sampling theorem, draw the signal, frequency graph.
Quantization: uniform quantization, in order to realize the magnitude of sinusoidal signal as an example for the 64 level uniform quantization non-uniform quantization, input A law PCM encoder sine signal, the sampling sequence, to be PCM encoded, the encoder is given The output code sequence
Code: A Case Study of the signal to achieve the 13 A line approximation law and international standards on the number of A law PCM coding quantization.

Description: 设x(n) = x1(n) + x2(n)，x1(n)是窄带信号，定义为x1(n) = sin(0.05πn +φ)，φ是在[0, 2π)区间上均匀分布的随机相位。x2(n)是宽带信号，它由一个零均值、方差为1的白噪声信号e(n)激励一个线性滤波器而产生，其差分方程为x2(n) = e(n) + 2e(n-1) + e(n-2)。
(1)计算x1(n)和x2(n)各自的自相关函数，并画出其函数图形。据此选择合适的延时，以实现谱线增强。
(2)产生一个x(n)序列。选择合适的μ值。让x(n)通过谱线增强器。画出输出信号y(n)和误差信号e(n)的波形，并分别与x1(n)和x2(n)进行比较。-Let x (n) = x1 (n)+ x2 (n), x1 (n) is a narrowband signal, is defined as x1 (n) = sin (0.05πn+φ), φ is in [0, 2π) uniformly distributed interval random phase. x2 (n) is a wideband signal, which consists of a zero mean and variance of a white noise signal e (n) incentive to produce a linear filter, and its differential equation is x2 (n) = e (n)+ 2e (n-1)+ e (n-2). (1) Calculation x1 (n) and x2 (n) each of the autocorrelation function and draw the graph of a function. Accordingly appropriate delay, in order to achieve line enhancement. (2) generating a x (n) sequences. Select the appropriate μ values. Let x (n) through line enhancer. Draw the output signal y (n) and the error signal e (n) of the waveform, respectively, and x1 (n) and x2 (n) for comparison.
