pyrex.custom.irex.frontends.bridge_rectifier_envelope_model(signal, cap=2e-11, res=500)

Model of a diode bridge rectifier envelope circuit.

Passes the input signal through a diode bridge rectifier envelope circuit consisting of four diodes in a diode bridge, a capacitor, and a resistor. The diode used is modeled after an HSMS 2852 diode.

Parameters

signalSignal

Signal object used as input to the circuit.

capfloat, optional

Capacitance (F) of the circuit’s capacitor C1.

resfloat, optional

Resistance (ohm) of the circuit’s resistor R1.

Returns

Signal

Output of the envelope circuit for the given input.
