Which constraint triggers increased phase noise in direct-conversion receivers?

💡 Explanation

Local oscillator jitter induces phase noise because the phase detector compares the incoming signal against the unstable local oscillator; therefore instability degrades signal clarity rather than cable bend or incorrect pilot tone selection.
