Latest Patents

One of Kanagawa's latest patents is a digital graphic equalizer. This invention allows for obtaining both a boost characteristic and an attenuation characteristic using band pass filters, each constituted by a digital filter and an adder. For the boost characteristic, an input signal is supplied to the first band pass filters, and the resultant filtered signals are added to the input signal by a first adder. For the attenuation characteristic, the output signal of a second adder is fed back to the second band pass filters, and the resultant filtered signals are added to the input signal by a second adder.

Another significant patent is a variable frequency characteristic circuit for a vehicular sound device. This circuit compensates for the frequency characteristics in an audio device within a vehicle. It utilizes a single operational amplifier, with different resonance circuits of varying frequencies connected from ground to either the inverting or non-inverting inputs. This design provides local peaks and dips, while two variable resistors connected in parallel between the inverting and non-inverting inputs allow for treble and bass control.
