Classes
struct	pulp::signal::BridgedTComponents
	Component values of the TR-808 bass drum's bridged-T network, in SI units (ohms, farads). More...
struct	pulp::signal::Q43Leakage
	Softplus fit of Q43's collector current against Vcomm (DAFx-14 Eq. More...
class	pulp::signal::BridgedTResonator
	The TR-808 bass drum's bridged-T network: one second-order system with three inputs (pulse shaper, feedback buffer, retrigger pulse) and two outputs (Vbt, the sound; Vcomm, the node that drives Q43's leakage). More...
