Hi All,I came to realise something odd about Nyquist frequency (a bit late though).When I generate it, it comes out only real. So I expected it to mirror around...

I know that a 3 dB hybrid can generate a 0 degree and 90 degree output ports.  Can I sample these two ports synchronized in time to generate my I & Q signals?...

In small satellite communication technique we can use optical spectrum (optical (laser) communication system). The common and simplest modulation techniques used...

Light computes any desired linear transform without a digital processor Kinda cool.

HelloI am building up a RF transceiver using integrated up/down converter chip.This particular chip requires a complex Intermediate Frequency as inputs for up conversion...

I asked the question about to recover signal from the real part of IFFT OFDM system before,Recover signal from the real part of IFFT.thanks for the responses from...

I'm simulating a Binary Orthognal Chirp Keying communication system in Matlab, with AWGN channel.Basically I'm sending the bit 0  by transmitting a down-chirp C0[n] ...

I'd like to add an upmixer software module to an existing commercially available DSP (Car Audio) with a Sharc chip. I see the Jtag header on the circuit board...

Can you find the illegal step in the following silly proof? Given: a=b$$ a^2=ab$$$$a^2-b^2 = ab-b^2$$$$(a+b)(a-b)=b(a-b)$$$$a+b = b$$$$b+b=b$$$$2b=b$$
