fm- frequency modulated am- amplitude modulated
Type IV Hyper sensitivity. AKA delayed hypersensitivity. Can be classified into: -contact -tuberculin -granuloma
hypersensitivity to light :) People with migraines have this, as well as phonophopia (hypersensitivity to sound).
AM = amplitude modulated. FM = frequency modulated.
Type II hypersensitivity is also known as cytotoxicity hypersensitivity and it may affect variety of organs and tissues. The antigens are endogenous and exogenous chemicals. Type III Hypersensitivity complex type of hypersensitivity and it may affect individual organs like skin, Liver etc.
a. velocity modulated tube b. frequency modulated tube c. Amplitude modulated tube d. simple triode
FM means Frequency Modulation.
Inhaled or ingested allergens usually cause immediate hypersensitivity reactions.
Allergens on the skin usually cause delayed hypersensitivity reaction.
It gives frequency modulated signal
