    Title: File Transfer client and server Description: Send or recieve files of any size or type between you and a peer. Displays bytes sent or recieved, return values of send() and recv(), bitrate in KBytes/Sec, and time remaining. SendFile and RecvFile functions can easily be added and used in your own code. I tested it ofcourse, a 73 mb self extracting rar archive from South Korea to Massachusetts at 96KB/s arrived fully operational.

  • 电子闹钟 clk: 标准时钟信号

    电子闹钟 clk: 标准时钟信号,本例中,其频率为4Hz; clk_1k: 产生闹铃音、报时音的时钟信号,本例中其频率为1024Hz; mode: 功能控制信号; 为0:计时功能; 为1:闹钟功能; 为2:手动校时功能; turn: 接按键,在手动校时功能时,选择是调整小时,还是分钟; 若长时间按住该键,还可使秒信号清零,用于精确调时; change: 接按键,手动调整时,每按一次,计数器加1; 如果长按,则连续快速加1,用于快速调时和定时; hour,min,Sec:此三信号分别输出并显示时、分、秒信号, 皆采用BCD 码计数,分别驱动6 个数码管显示时间; alert: 输出到扬声器的信号,用于产生闹铃音和报时音; 闹铃音为持续20 秒的急促的“嘀嘀嘀”音,若按住“change”键, 则可屏蔽该音;整点报时音为“嘀嘀嘀嘀—嘟”四短一长音; LD_alert: 接发光二极管,指示是否设置了闹钟功能; LD_hour: 接发光二极管,指示当前调整的是小时信号; LD_min: 接发光二极管,指示当前调整的是分钟信号

    P3.20. Consider an analog signal xa (t) = sin (2πt), 0 ≤t≤ 1. It is sampled at Ts = 0.01, 0.05, and 0.1 Sec intervals to obtain x(n). b) Reconstruct the analog signal ya (t) from the samples x(n) using the sinc interpolation (use ∆ t = 0.001) and determine the frequency in ya (t) from your plot. (Ignore the end effects.) C) Reconstruct the analog signal ya (t) from the samples x (n) using the cubic spline interpolation and determine the frequency in ya (t) from your plot. (Ignore the end effects.)
