I have a periodically operated 1st order low pass filter circuit as shown below -

enter image description here

I am interested in obtaining the transfer function from the input to the output. Can you provide with me some ideas on how to approach the problem?

I know that when the switch is high, it is an LPF and when switch is low, the output is zero. This will give me two differential equations relating the input and output. But how do I express vin in terms of vout, in general?
