Query: A Step towards Unveiling the Nature of Three Cataclysmic Variables: LS
  Cam, V902 Mon, and SWIFT J0746.3-1608   We have carried out detailed time-resolved timing analyses of three
cataclysmic variables (CVs) namely LS Cam, V902 Mon, and SWIFT J0746.3-1608,
using the long-baseline, high-cadence optical photometric data from the
Transiting Exoplanet Survey Satellite (TESS). Our analysis of LS Cam
observations hints the presence of a superorbital period of $\sim$
4.025$\pm$0.007 d along with negative and positive superhump periods of $\sim$
3.30 h and 3.70 h, respectively. These results can be explained as an
interaction of nodal and apsidal precession of the accretion disc with orbital
motion. For the other two sources, V902 Mon and SWIFT J0746.3-1608, we have
found evidence of a beat period of 2387.0$\pm$0.6 s and 2409.5$\pm$0.7 s,
respectively, which were not found in earlier studies. Our results presented in
this study indicate the change in the accretion mode during the entire
observing period for both sources. For V902 Mon, an apparent orbital period
derivative of (6.09 $\pm$ 0.60) $\times 10^{-10}$ was also found. Moreover, the
second harmonic of orbital frequency dominates the power spectrum of SWIFT
J0746.3-1608, suggestive of ellipsoidal modulation of the secondary star.
Present analyses suggest that LS Cam could be a superhumping CV whereas V902
Mon and SWIFT J0746.3-1608 are likely to be variable disc-overflow accreting
intermediate polars.
