有没有用过语音猫的朋友。 最近弄到一块语音猫,在语音猫的speaker、MIC插孔上插上我的耳机和麦克风,通过超级终端可以拨出电话号码,对方可以接听,我可以听到对方的讲话,但是对方听不到我的麦克风里的声音。

The SP486 and SP487 are low–power quad differential line drivers meeting RS-485 and RS-422 standards. The SP486 features a common driver enable control the SP487 provides independent driver enable controls for each pair of drivers. Both feature tri–state outputs and wide common–mode input range. Both are available in 16–pin plastic DIP and SOIC packages.

SPREAD SPECTRUM MODULATION TECHNIQUES -spread spectrum - those modulation methods that are producing a signal whose spectrum is more wider than of the data signal, the occupied frequency band being independent by the signal of data band. -The signals with spread spectrum of direct sequence type BPSK (BPSK-DS-SS) -The signals with spread spectrum of direct sequence type QPSK – DS–SS - Frequency hopping spread spectrum signals (FH-SS)

The code performs a number (ITERS) of iterations of the Bailey s 6-step FFT algorithm (following the ideas in the CMU Task parallel suite). 1.- Generates an input signal vector (dgen) with size n=n1xn2 stored in row major order In this code the size of the input signal is NN=NxN (n=NN, n1=n2=N) 2.- Transpose (tpose) A to have it stored in column major order 3.- Perform independent FFTs on the rows (cffts) 4.- Scale each element of the resulting array by a factor of w[n]**(p*q) 5.- Transpose (tpose) to prepair it for the next step 6.- Perform independent FFTs on the rows (cffts) 7.- Transpose the resulting matrix The code requires nested Parallelism.
