34\,\mathrm{kHz}

. It is digitised by a

10

-bit sample-and-hold system sampling at

f_s = 20\,\mathrm{kHz}

. ((a)) Estimate the frequency at which this tone appears in the recorded data. ((b)) Estimate the maximum rms aperture jitter the sample-and-hold may have if the recorded amplitude of the

34\,\mathrm{kHz}

tone is not to be degraded below the

10

-bit full-scale signal-to-noise ratio.
