## Modulation

Modulation. Suppose we take the product of two signals:. In general, for any function X(f) , we have. In general, for DSB-SC, we have. X. m(t). x c (t). cos w c t. Phase Modulation. Equating the real and the imaginary parts, we have. A general sketch of the spectrum is shown below.

## Power spectral density (PSD)… of ASK,PSK and FSK

Power spectral density (PSD)… of ASK,PSK and FSK. Note that the bandwidth of FSK is higher than ASK or PSK . Conclusion is that ;polar signaling is the most efficient scheme from the point of view of the noise immunity.
