<p>providing a frequency and phase reference for extracting the message signal from the sidebands. In some modulation systems based on AM, a lower transmitter power is required through partial or total elimination of the carrier component, however receivers for these signals are more complex because they must provide a precise carrier frequency reference signal (usually as shifted to the <a href="page.php?w=intermediate_frequency">intermediate frequency</a>) from a greatly reduced "pilot" carrier (in <a href="page.php?w=reduced-carrier_transmission">reduced-carrier transmission</a></p><p>
