Target detection frequencies: How to calculate the subharmonic and harmonic of f
(assuming the guaranteed oscillation frequency error is ± 1%)
The following shows the recommended configuration when f
(assuming the oscillation frequency error and the OFD capable of detecting are 10% totally).
24MHz
10MHz
Sub-harmonic (allowing for the maximum high-frequency oscillator error)
Harmonic (allowing for the minimum high-frequency oscillation error)
= 24 MHz × (1-0.01) ×2 = 47.52 MHz
f
= 24 MHz × (1+0.01) ÷2 = 12.12 MHz
