• Direct-conversion receiver — A direct conversion receiver (DCR), also known as homodyne, synchrodyne, or zero IF receiver, is a radio receiver design that demodulates the incoming radio signal using synchronous detection driven by a local oscillator whose frequency is… …   Wikipedia

• Receiver (radio) — This article is about a radio receiver, for other uses see Radio (disambiguation). A radio receiver is an electronic circuit that receives its input from an antenna, uses electronic filters to separate a wanted radio signal from all other signals …   Wikipedia

• Radio receiver design — is a complex topic which can be broken down into a series of smaller topics. A radio communication system requires two tuned circuits each at the transmitter and receiver, all four tuned to the same frequency. [Cheney, M., Uth, R., Glenn, J.… …   Wikipedia

• Superheterodyne receiver — A 5 tube superheterodyne receiver made in Japan around 1955 In electronics, a superheterodyne receiver (sometimes shortened to superhet) uses frequency mixing or heterodyning to convert a received signal to a fixed intermediate frequency, which… …   Wikipedia

• Software-defined radio — A Software Defined Radio (SDR) system is a radio communication system where components that have typically been implemented in hardware (i.e. mixers, filters, amplifiers, modulators/demodulators, detectors. etc.) are instead implemented using… …   Wikipedia

• Local oscillator — A local oscillator is an electronic device used to generate a signal normally for the purpose of converting a signal of interest to a different frequency using a mixer. This process of frequency conversion, also referred to as heterodyning,… …   Wikipedia

• Product detector — A product detector is a type of demodulator used for AM and SSB signals. Rather than converting the envelope of the signal into the decoded waveform like an envelope detector, the product detector takes the product of the modulated signal and a… …   Wikipedia

• Homodyne detection — is a method of detecting frequency modulated radiation by non linear mixing with radiation of a reference frequency, the same principle as for heterodyne detection.In optical interferometry, homodyne signifies that the reference radiation (the… …   Wikipedia
