WebThe zero-Doppler cut of the ambiguity function for the hybrid linear-tangent FM shows that the first null occurs at around 1.5 microseconds. This means that the range resolution is degraded to 225 m compared to 150 m for linear FM with the same bandwidth. The range sidelobe level, however, is more than 10 dB lower. WebShow more.

WebThe first null of the sinc function occurs at frequency equivalent to the bit rate of the PN code. For example, a bit rate of 10 MBits/s translates to a frequency at the first null of 10 Mhz. Since the magnitude of the spectrum is symmetrical around DC, the null-to-null bandwidth is twice the bit rate - 20 MHz in the example given. WebFor no aliasing: fs = 2B, where B is the bandwidth of the analog signal that is to be converted. Bandwidth of the PCM waveform is bounded by.
