Kenwood Unlock the Power of DSP Technology in TS-480 for Enhanced Communication

Features of the Built-in DSP

●DSP circuit

The digital signal processor equipped on the TS-480 is the 16-bit fixed-point TMS320VC5402 from Texas Instruments, which offers excellent value for the money. Running at 100MHz, it provides double-precision arithmetic operations (equivalent to 32-bit processing), making it more than capable of serving as an AF DSP. Thanks to this, the TS-480 offers many powerful features of use in HF operations.

● Ideal for mobile operations: DNL NEW

When you hear the crackling of ignition and other types of pulse noise, it is possible to remove it using the noise blanker (NB); however, this does not work in all cases. Depending on the type of noise, or if there is a very strong signal close by, the pulse noise may remain and be demodulated. This can result in an unpleasant sound being emitted from the speaker, thus reducing the clarity of your target signal. In such cases, the DNL (digital noise limiter) can reduce pulse noise that has been demodulated at the AF stage, effectively extracting your target audio signal.

Fig.13 is a block diagram illustrating in principle how the DNL operates.
