Abstract
An expression describing the variance of shot noise is derived for deterministic, time-varying photon rates on a semiclassical basis. This is done both for the case with and without postprocessing in the electrical regime. It is shown how the results are related to the traditional shot-noise formula and under which (restricted) conditions the well-known formula may be applied. This becomes significant when signal-to-noise ratios have to be calculated. An example related to optical heterodyning demonstrates similarities and differences between the traditional formula and the new results.

- The weight of Dirac impulses is denoted by a hat [e.g., Σ⁁(0)]; the spectrum Σ(jω)thus equals Σ⁁(0)δ(ω)+ Σ ˜(jω).
- The duration and bandwidth of a signal x(t)can be defined in various ways. We use the following definitions fulfillingthe time–bandwidth product relation B_{x}T_{x}≥1/2: B_{x}=−∞ ∞|X(jν)|^{2}dν2|X(jν)|_{max}^{2}, T_{x}=−∞ ∞|x(t)|^{2}dt|x(t)|_{max}^{2}. In these relations, X(jν) standsfor the Fourier transform of x(t).

- As h(t) is real, the magnitude of its spectrumis even and the phase is odd; this means |H(0)|=H(0).
- Note that I_{0} is defined to bethe direct current before the filter f(t) according toEq. (12).
- This definition is not the only reasonable one; another well-motivateddefinition could be SNR=〈s(t)〉_{e}^{2}σ_{i}^{2}(t), which does not yield thesame results as Eq. (20), however.
- This is the case in a heterodyne detection arrangement, forinstance, if the detector works well below its cutoff frequency, resultingin |H(jω)|≈e, and if |F(jω)|, representing a fairly narrow bandpass filter, equals unity in the passband.
- These quantities are of dimension W/m^{2}.
- The procedure of making the signal x˜(t)periodic for the definition of a time average may look strange at a firstglance. However, it is seen in the main text that it in fact unifies the derivationsfor time-limited and time-unlimited signals.
