LC Filter Bank Oscillator 2

This design utilizes the way capacitor in series and coils in parallel are added up to get the total capacitance and inductance 1 / (1/x1 + 1/x2 + ... +1/xn), to counter the nonlinear function for the resonance frequency of an LC circuit 1 / ( sqrt(L*C) * 2*pi ). This enables the 4 pairs of switches, each "enabling" or "disabling" a pair consisting of a capacitor and an inductor, to be controlled in a binary pattern, where one bit corresponds to a fixed change in frequency. * The step size in this configuration is 100kHz. * The span is 100kHz - 1.6MHz. * The formula for the frequncy is: 100kHz + bin_val * 100 kHz * The binary value is shown in the display. Use up/down/reset bottons to change frequency.
