PSpice; Simple ADC/DAC model for DSP modelling

[Klaus Kragelund]

Hi

I would like to simulate a FIR filter in Orcad PSpice and the method I
have found is to:

1 Add a sample/hold circuit
2 Add a ADC
3 Feed ADC directly to DAC
4 Use some transmission lines to get the delayed filter variables
5 Apply the filter to these variable

But, is there a simpler way to do this. Perhaps some fancy ABM block to
do the zero order hold and quantization of the converter?

Thanks

Klaus
