Model second-, third-, or fourth-order passive loop filter
Mixed-Signal Blockset / PLL / Building Blocks
The Loop Filter subsystem block is a passive filter whose order can vary from two to four. In a phase-locked loop (PLL) system, the subsystem filters the output of Charge Pump block and delivers the control voltage to a VCO block to generate required frequency signal.
