Right. But it's not simple to build an analog low pass filter with a cutoff frequency of 1/100 seconds. The modern approach is to use a small processor and a DAC. The hard part is getting enough effective bits out of the DAC. The archives are full of suggestions about which chip to use. For a home brew setup, you can trade bits for tuning range if you are willing to fiddle an analog pot occasionally when your crystal drifts out of tuning range as it ages. -- These are my opinions.
