What is the transfer function of VCO in simulink? How to compute Kvco if my settings of VCO are 1000/Hz?
 

I want to know the method to compute the value of Kvco
 

A VCO is described by the TF= K/s. what would you substitute for K?
 

This is precisely my question, VCO setting in simulink is 1000Hz/V , does this mean Kvco is 1000*2*pi rad/v-s assuming VCO is perfectly linear.
 

Kvco is to be treated for frequency not angular? Now what is the value to assume for Kvco. Example would give more insight to me

Again, it depends on model formulation.

I can not understand what you want to mean at all.
Only you know what value should be applied as Kvco.

See **broken link removed**
 

I was confused over definition of KVco which says it is delta(f)/delta(v) where f can be expressed as rad/s. I was under impression that if my VCO is linear in frequency range ( 0-100KHz) for a dc-input 0-10V, then KVco should wok out to be 10KHz/V or KVco is 20*3.14 *1000rad/s/v. Is this correct way of interpretation
