相关函数法该方法先由序列估计出自相关函数R,然后对其进行傅立叶变换,得到功率谱估计。当延时和数据长度相比很小的时候可以有良好的估计精度。

把R、L、C转换成频率信号f,转换的原理分别是RC振荡电路和LC电容三点式振荡电路。单片机计数得出被测频率,由该频率计算出各个参数值,数据处理后,送显示。

Application Note Abstract This Application Note introduces a complete and detailed PSoC® project. Telephone Call Logger keeps the detailed record of approximately 945 phone calls (7-digit number is assumed to be one phone call) including date, start time and the duration of the phone call in the PSoC device. Users can get this detailed report into the PC environment by using free software, which is included in the project file. When records reach near full capacity of the Flash memory, an LED will turn on to show that it is necessary to backup the data. Software gets the data from PSoC, organizes it and prepares a printable version. Additionally, it sends the date and time information to the PSoC. The external parts in this project can be obtained easily in the market.

This project aim was to build wireless software modem for data communication between two computers using an acoustic interface in the voice frequency range (20Hz– 20,000Hz). The transmitting antenna is a speaker (frequency response of: 90Hz – 20,000Hz) and the receiving antenna is a microphone (frequency response of: 100Hz – 16,000Hz). The test files used as information files were text files. This goal was attained both in an incoherent scheme and in a coherent scheme. Build under Matlab code, our modem uses OFDM (orthogonal frequency division multiplexing) modulation, synchronization by LMS sequence, channel estimation (no equalizer) via pilot tones. The symbols are either PSK or ASK for a constellation size of 2 or 4. To optimize the probability of error, these symbols were mapped using Gray mapping. Report

The main purpose of this project is to add a new scheduling algorithm to GeekOS and to implement a simple synchronization primitive (semaphore). As you might have already noticed, GeekOS uses a simple priority based preemptive Round Robin algorithm. In this project, you will change this to a multilevel feedback scheduling. In addition, you will provide user programs with semaphores, a means to check the system s current time and a mechanism for passing command-line arguments
