acpr_vr()

Computes the adjacent-channel power ratio following a Circuit Envelope simulation

Syntax
ACPRvals = acpr_vr(voltage, resistance, mainCh, lowerAdjCh, upperAdjCh, winType, winConst)

Arguments

Examples

Vmain_fund=vOut[1]
mainlimits={-16.4 kHz,16.4 kHz}
UpChlimits={mainlimits+30 kHz}
LoChlimits={mainlimits-30 kHz}
acpr_ey=acpr_vr(Vmain_fund,50,mainlimits,UpChlimits,LoChlimits)

where vOut is the named connection at a resistive load. The {} braces are used to define vectors.

Note vOut is a named connection on the schematic. Assuming that a Circuit Envelope simulation was run, vOut is output to the dataset as a two-dimensional matrix. The first dimension is time, and there is a value for each time point in the simulation. The second dimension is frequency, and there is a value for each fundamental frequency, each harmonic, and each mixing term in the analysis, as well as the baseband term. vOut[1] is the equivalent of vOut[::, 1], and specifies all time points at the lowest non-baseband frequency (the fundamental analysis frequency, unless a multi-tone analysis has been run and there are mixing products). For former MDS users, the notation "vOut[*, 2]" in MDS corresponds to the notation of "vOut[1]".

Notes/Equations

Used in Adjacent-channel power computations.
The user must supply a single complex voltage spectral component (for example, the fundamental) across a resistive load versus time and the load resistance. The user must also supply the upper and lower adjacent-channel and main-channel frequency limits, as offsets from the spectral component frequency of the voltage. These frequency limits must be entered as two-dimensional vectors. An optional window and window constant may also be supplied, for use in processing non-periodic data.
