So if your design fits inside 10cm x 10cm (a common limit for cheap PCBs), and your components are worst case (diagonal corners, about 14 cm) your wavelength is 16x14cm = 2.24 metres.

C Z = 1 / (2 * π * f C * R L). Where R Z is the Zobel resistance and C Z is the Zobel capacitance, R L is the impedance of the loudspeaker, f C is the desired cutoff frequency. For our 27.4-kHz ...

If you recall the matching condition L/R=2RC and set L=2R2C, the cutoff frequency for the circuit in Figure 1b is f 2 =(2.05)/(2uppercase pi ÷2RC). If you compare this expression with f C =1/2 ...

Non-Foster circuit: An active network design that introduces negative impedance components to counteract the bandwidth limitations inherent in passive circuits. Antenna matching: The process of ...
