This is very old germanium diode and nomenclature comes before a standard had been established for semiconductors. They modeled 0A after the vaccum tubes where 0 - zero means 0Volts filament voltage and A meant single diode.
Latter , semiconductor nomenclature come where the first number was telling a number of PN junctions followed by N (this is for US), Japanese and Europeans had different naming standards
0a79 ( germanium diode )in glass construction form is used in AM detector circuits.
AM demodulators are electronic circuits or devices used to extract the original audio or information signal from an amplitude-modulated (AM) carrier wave. They work by detecting variations in the amplitude of the carrier signal, which correspond to the information being transmitted. Common types of AM demodulation techniques include envelope detection and synchronous detection. These demodulators are widely used in AM radio receivers and other communication systems that utilize amplitude modulation.
An AC diode, often referred to as a rectifier diode, is used to convert alternating current (AC) into direct current (DC). It allows current to flow in one direction while blocking it in the opposite direction, effectively transforming the AC waveform into a pulsating DC signal. This is essential in power supply circuits, where devices require a stable DC voltage for operation. Diodes are also used in various applications such as signal demodulation and voltage regulation.
A crystal detector is a diode, often used in non-powered radio receivers. It conducts at a much lower voltage than a typical silicon diode, making it easier to generate the signal amplitude required from the tuning circuit.
It's a high voltage diode, typically used in microwave ovens.

In case of coherent demodulation carrier used for demodulation purpose is in phase and frequency synchronism with carrier used for modulation purpose. For non-coherent demodulation it is not in synchronism.

yes, diode can be used as rectifier diode to convert ac to dc

A diode is used primarily as a Rectifier
a diode is any electronic device that conducts current significantly better in one direction than the other. it can be a vacuum tube diode, a gas filled tube diode, a point contact semiconductor diode, a junction semiconductor diode, any of several metal oxide diodes, etc.typical applications are:AC power rectifiersAmplitude modulated radio signal demodulators (detectors)Gas filled tube diodes used to be used in certain types of digital counters and computer registersDigital logic gatesSign detection circuits in analog computersVoltage clamps and clippersFrequency modulated radio amplitude limiters to remove static and interferenceetc.
yes ofcourse diode can be used as rectifier but it's an uncontrolled rectification.
Diode in simple terms is a "One Way" Device, i,e it allows current to flow thru in one direction only.Diodes are the most indispensable part in the electronic/electric World.
