Pete You can usually do much better than that. The Collins paper indicates how. http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?isnumber=10665&arnumber=494304&type=ref <http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?isnumber=10665&arnumber=494304&type=ref> (I know you have to purchase it or perhaps photocopy it. - but its well worth the effort) I have extended the theory to include the case where the input noise spectral density is not the same for all finite gain limiter stages. I also have a few spreadsheets which can be used to calculte the optimum gain distribution and corresponding filter bandwidths etc both for the restricted case that Collins analyses and the more general case. The Collin's paper indicates how much better one can do with an optimised cascade of finite gain filtered limiter stages as opposed to the relatively conventional design in the Dick paper. With high frequency signals one can use a bandpass filter at least for the first couple of low gain limiter stages.
