A diode bridge modulator is one kind of balanced modulator.
zener diode :zener diode operates under reverse bias voltageideal diode :ideal diode operates under forward bias voltage
The dynamic resistance of a diode, be it zener or otherwise, will be different from its static resistance because a diode is not a resistor, and resistance is not a function of current flow. It is a diode, and a diode has its own characteristic voltage to current curve, forward and, in the case of a zener, reverse.
Diodes are largely used for changing AC into DC. A half wave diode bridge will use two diodes for this purpose. A full wave bridge uses four diodes to accomplish this task.See related links below.
Measuring ripple frequency would determine if a diode were open in a bridge rectifier circuit because the ripple frequency is normally twice the input frequency in a functioning full wave bridge rectifier. If one diode were open, the ripple frequency would only be the input frequency. Note: This is true for single phase or bi-phase operation. Three phase operation is more complex, but still doable - You would expect three times input frequency in normal state, and two times (asymmetric) with one open diode.
No. An ordinary diode, be it silicon or germanium, conducts in one direction only, whereas a zener diode conducts in both directions, but at different voltages. An ordinary diode is used to rectify, using its forward bias characteristics, while a zener diode is used to regulate, using its reverse bias characteristics.
the output from a balanced modulator consists of modulating freq also. this can be eliminated in a diode modulator by adding two more diodes, making a diode ring. therefore called ring modulator

A diode modulator is a type of AM modulator constructed using diodes. One type of diode modulator is the ring modulator shown in the image.

A diode is used as a rectifier, clipper and to get square wave form. The combination of diode (bridge) is used for full wave rectification. It also used as a voltage controlar. Different types of diodes have different uses in different appliences.

Merits a diode bridge rectifier is simple to build
Bridge diodes are generally used in a bridge rectifier to convert AC into DC.
How to test a diode bridge ? Diode bridge is a device is used to convert an AC signals (say AC voltage) to DC output (say DC voltage). So, to test it, you can apply a AC voltage v = Vm Sin (wt) at its 2 inputs and measure DC output voltage Vdc.
