Explanation: The desired amount of multiplication can be obtained by properly selecting a divide by N-network. For example, to obtain the output frequency fout=5×fin, a divide by N = 5 network is needed. 2. Calculate the output frequency in a frequency multiplier if, fin = 200Hz is applied to a 7 divide by N-network.
A. 1.2kHz
B. 1.6kHz
C. 1.2kHz
D. 1.9kHz
Answer:A
Explanation: The desired amount of multiplication can be obtained by properly selecting a divide by N-network. For example, to obtain the output frequency fout=5×fin, a divide by N = 5 network is needed. 2. Calculate the output frequency in a frequency multiplier if, fin = 200Hz is applied to a 7 divide by N-network.
A. 1.2kHz B. 1.6kHz C. 1.2kHz D. 1.9kHz
Explanation: Since the VCO is actually running at a multiple of input frequency. fout=divide by N-network x fin=7x200Hz=1400Hz
