Which of the following is an advantage of a digital signal processing (DSP) filter compared to an analog filter?

Digital Signal Processing (DSP) allows filtering to be done through software algorithms rather than fixed hardware components like capacitors and inductors. This means a single DSP system can instantly switch between many different bandwidths and highly customized filter shapes simply by changing mathematical parameters. Analog filters, on the other hand, are physically fixed. To get a variety of filter shapes or bandwidths in an analog radio, you would need to install multiple separate hardware crystal or mechanical filters. DSP removes this hardware limitation, giving operators immense flexibility to tailor the filter to the specific interference conditions.
