watt_to_dbm#

sionna.phy.utils.watt_to_dbm(x_w: float | torch.Tensor, precision: Literal['single', 'double'] | None = None, device: str | None = None) → torch.Tensor[source]#

Converts the input [Watt] to dBm.

Parameters:

x_w (float | torch.Tensor) – Input value in Watt.
precision (Literal['single', 'double'] | None) – Precision used for internal calculations and outputs. If set to None, precision is used.
device (str | None) – Device for the output tensor. If None and x_w is a tensor, uses the device of x_w. Otherwise uses device.

Outputs:

x_dbm – Input value converted to dBm.

Examples

import torch
from sionna.phy.utils import watt_to_dbm

x = torch.tensor(1.0)  # 1 Watt
print(watt_to_dbm(x).item())
# 30.0
