数字频率计的设计可以分为测量计数和显示。其测量的基本原理是计算一定时间内待测信号的脉冲个数，这就要求由分频器产生标准闸门时间信号，计数器记录脉冲个数，由控制器对闸门信号进行选择，并对计数器使能断进行同步控制。控制器根据闸门信号确定最佳量程。-The design of digital frequency meter can be divided into measurement and display count. The basic principle of its measurement is calculated under test signal within a certain period of time the number of pulses, which have a standard requirement by the divider gate time signal pulse counter records the number of signals from the controller to choose the gates and counters to make off synchronous control can be carried out.Controller based on the gate signal to determine the optimum range.

在电子技术中，频率是最基本的参数之一，又与许多电参量的测量方案、测量结果都有十分密切的关系，因此频率的测量就显得更为重要。测量频率的方法有多种,其中电子计数器测量频率具有精度高、使用方便、测量迅速，以及便于实现测量过程自动化等优点，是频率测量的重要手段之一。在本次毕业设计中我们选择使用单片机来制作数字频率计，并在实际制作中采用了直接测频法。利用延时产生的时基门控信号来控制闸门，通过在单位时间内计数器记录下的脉冲个数计算出输入信号的频率，最终送入LCD中显示。这样制作出来的频率计不仅可以满足设计题目的参数要求，而且具有了单片机的稳定性和成熟性，且控制能力强，是一种低成本，高可靠的设计方案。-In electronic technology, the frequency is one of the most basic parameters, but also with a number of electrical parameters of the measurement program, the measurement results have a very close relationship between the frequency of measurement, therefore it is even more important. Measurement of the frequency of a number of means, electronic measurement of the frequency counter with high precision, easy to use, rapid measurement, and measurement is easy to realize the advantages of process automation is an important means of measuring the frequency of one. Graduates in this design we have chosen to make use of single-chip digital frequency meter, and used in the actual production of a direct

Wavelets have widely been used in many signal and image processing applications. In this paper, a new
serial-parallel architecture for wavelet-based image compression is introduced. It is based on a 4-tap wavelet
transform, which is realised using some FIFO memory modules implementing a pixel-level pipeline
architecture to compress and decompress images. The real filter calculation over 4 ・ 4 window blocks is
done using a tree of carry save adders to ensure the high speed processing required for many applications.
The details of implementing both compressor and decompressor sub-systems are given. The primarily analysis
reveals that the proposed architecture, implemented using current VLSI technologies, can process a
video stream in real time.-Wavelets have been widely used in many sign al and image processing applications. In this p aper. a new serial-parallel architecture for wavele t-based image compression is introduced. It is based on a 4-tap wavelet transform. whic
