%% LC Bandpass Pi



%Using a Ladder Filter Block to Filter Gaussian Noise
% 

% This example provides complex random noise in Gaussian form as input to 
% an LC Bandpass Pi block. A DSP System Toolbox  Spectrum Scope block plots
% the filtered output.

% The DSP System Toolbox fallback for tm_signalprocessingblockset  Random
% Source block produces frame-based output at 512 samples per frame. Its 
% Sample time parameter is set to 1.0e-9. This sample time must match the 
% sample time for the physical part of the model, which you provide in the 
% Input Port block diagram.
% The Input Port block specifies Finite impulse response filter length as 
% 256, Center frequency as 700.0e6 Hz, Sample time as 1.0e-9, and Source
% impedance as 50 ohms.

%The LC Bandpass Pi block provides the inductances for three inductors, in
%order from source to load, [1.4446e-9, 4.3949e-8, 1.4446e-9]. Similarly, 
%it provides the capacitances for three capacitors [3.5785e-11, 1.1762e-12,
%3.5785e-11]. 



%The following plot shows a sample of the baseband-equivalent RF signal 
%generated by this LC Bandpass Pi block. Zero (0) on the frequency axis 
%corresponds to the center frequency specified in the Input Port block. 
%The bandwidth of the frequency spectrum is 1/sample time. You specify the 
%Sample time parameter in the Input Port block.
%The Axis Properties of the Spectrum Scope block have been adjusted to show
%the frequencies above and below the carrier. The Minimum Y-limit parameter
%is -90, and Maximum Y-limit is 0.
