    How to Build a Costas Receiver?

    Hello, is anyone can guide me to built a costas receiver. At the input of a mixer the LO and RF signal creates an IF signal. This IF is the frequency difference of LO and RF irrespective of their position of frequency spectrum, i mean IF=LO-RF or IF=RF-LO. I need to track this IF signal at the...

    How to calculate signal and noise power

    hello, i have a signal current I(t)=Acos(wt+theta) How can i calculate the signal power and noise power individually? thanks Reza

    Relation between phase spectrum and frequency spectrum

    assume, The frequency noise process f(t)is white then S_{f} (f)=N_{0} Since the phase is the integral of the frequency, the phase becomes \phi(t)=2*pi*\int^{0}_{t}f(\tau)d(\tau) if phase spectrum is S_{\phi}(t) what is the relation now, i mean how i can express the phase spectrun in...

    Relation between phase spectrum and frequency spectrum

    assume, The frequency noise process f(t)is white then S_{f} (f)=N_{}0 Since the phase is the integral of the frequency, the phase becomes \phi(t)=2\pi\int^{0}_{t}[f(\tau)d(\tauu)] if phase spectrum is S_{\phi}(t) what is the relation now, i mean how i can express the phase spectrun in...
