·詳細說明:DTMF檢測程序。定點計算,可移植到DSP上。 Usage: dtmf filename -DTMF examination procedure. The fixed point calculation, may transplant to DSP on. Usage: Dtmf filename 文件列表: alaw.cpp alaw.h &nb
Routine mampres: To obtain amplitude response from h(exp(jw)).
input parameters:
h :n dimensioned complex array. the frequency response is stored
in h(0) to h(n-1).
n :the dimension of h and amp.
fs :sampling frequency (Hz).
iamp:If iamp=0: The Amplitude Res. amp(k)=abs(h(k))
If iamp=1: The Amplitude Res. amp(k)=20.*alog10(abs(h(k))).
output parameters:
amp :n dimensioned real array. the amplitude-frequency response is
stored in amp(0) to amp(n-1).
Note:
this program will generate a data file "filename.dat" .

用win32匯編編寫的類木馬的東西,運行后在機子上打開23端口,用telnet登陸,可以運行下列命令:
open filename - open the file or program
msg message - place message plainly over screen
box message - show within a messagebox
cdopen - to open CDROM drive door
cdclose - to close CDROM drive door
bye - terminate connection, handles one user at a time
kill - terminate sparczerver
