WebOct 10, 2024 · To satisfy such requirements, the MSK spectrum can be easily manipulated by using a pre-modulation low pass filter (LPF). The pre-modulation LPF should have the following properties and it is found that a Gaussian LPF will satisfy all of them [1]. Sharp cut-off and narrow bandwidth – needed to suppress high frequency components.
