Abstract
A prescription attenuator comprising a plurality of cascaded L-pad sections coupled together to form an attenuator network wherein each cascaded section includes a single pole switch for activating its respective section. The network impedance values are selected so that single L-pad section activations produce actual attenuations slightly more than an ideal level of attenuation wherein multiple section activations tend to keep the error evenly distributed about the ideal level of attenuation.
