| Abstract: | A new technique is described in which stray-insensitive SC lowpass ladder filters of the LDI type are designed without the need for network synthesis. These filters exactly simulate the response of a unit element cascade prototype filter and may be designed with a usable frequency range up to one half the sampling frequency. This design procedure requires no more than simple hand calculation. |
