Explanation: The voltage to frequency conversion factor, Kv = △fo/△Vcc= 8×fo/Vcc = (8×155)/10=124. 13. Find the equation for change in frequency of VCO?
A. △fo = (2×△Vc)/(RT×CT×Vcc)
B. △fo = △Vc/(4×RT×CT×Vcc)
C. △fo = △Vc/(2×RT×CT×Vcc)
D. △fo = (4×△Vc)/(RT×CT×Vcc)
Answer:A
Explanation: The voltage to frequency conversion factor, Kv = △fo/△Vcc= 8×fo/Vcc = (8×155)/10=124. 13. Find the equation for change in frequency of VCO?
A. △fo = (2×△Vc)/(RT×CT×Vcc) B. △fo = △Vc/(4×RT×CT×Vcc) C. △fo = △Vc/(2×RT×CT×Vcc) D. △fo = (4×△Vc)/(RT×CT×Vcc)
Explanation: The original output frequency, fo =2×[Vcc-Vc+△Vc]/[RT×CT×Vcc].
