The objective of this projectis to design, model and simulate an autocorrelation generator circuit using 4-bit LFSR. the register and LFSR will used D flip-flop and some gates. By the autocorrelation concept, there should be 2 same length vectors, for calculating the autocorrelation , we have to design the register for storing the original vector and the shifter for make time DELAY.

數(shù)字選臺收音機 注意： （1）遙控發(fā)射芯片用TC9012/TC9243 經(jīng)常用到的還有UPD6121和LC7461，它們的不同只處在于引導碼的時間不同或者數(shù)據(jù)位的個數(shù)不同，接受原理基本一樣。將本程序的相關位置修改就可以通用。 系統(tǒng)時鐘22.1184MHZ，如果用其他的時鐘請將DELAY.c文件中的定時器裝載值修改一下 （2） 鍵盤檢測在VFD程序中，16312可以驅(qū)動VFD，另外外部可接24個按鍵，并將按鍵值放到 其內(nèi)部的存儲中，使用時只須發(fā)命令讀即可。 （3） 由于時間原因，只給出調(diào)幅波段的自動搜臺功能，調(diào)頻的自動搜臺程序和調(diào)幅一樣，自己寫了。 （4）主要用在組合機和功放機上的收音頭大部分以LC72171做鎖象環(huán)，LA1823做高中頻處理 和音頻解調(diào)，但是有的數(shù)調(diào)收音頭把鎖象環(huán)和高頻處理做在一起，典型的有TEA5757和TEA5756 TEA5757采用了一種所謂的自動調(diào)諧系統(tǒng)，在自動搜索時無須讀中頻，簡化了程序。

Mobile phones are constantly decreasing in size, thereby complicating the acoustical functionality. Signal processing methods can be used to partially mitigate this problem. In this paper we suggest a method which uses multiple spectral subtraction functions and two microphones, introducing only a short signal DELAY.

This leon3 design is tailored to the Altera NiosII Startix2 Development board, with 16-bit DDR SDRAM and 2 Mbyte of SSRAM. As of this time, the DDR interface only works up to 120 MHz. At 130, DDR data can be read but not written. NOTE: the test bench cannot be simulated with DDR enabled because the Altera pads do not have the correct DELAY models. * How to program the flash prom with a FPGA programming file 1. Create a hex file of the programming file with Quartus. 2. Convert it to srecord and adjust the load address: objcopy --adjust-vma=0x800000 output_file.hexout -O srec fpga.srec 3. Program the flash memory using grmon: flash erase 0x800000 0xb00000 flash load fpga.srec

The present paper deals with the problem of calculating mean DELAYs in polling systems with either exhaustive or gated service. We develop a mean value analysis (MVA) to compute these DELAY figures. The merits of MVA are in its intrinsic simplicity and its intuitively appealing derivation. As a consequence, MVA may be applied, both in an exact and approximate manner, to a large variety of models.

This example streams input from a ADC source to a DAC. An analog signal is acquired block-by-block into SDRAM from the ADC (an AD9244 in this example). The frames are then output with a one-frame DELAY to the DAC (an AD9744 in this example). In this example, no processing is done on the frames. They are passed unaltered.
