When choosing an RF instrument, it is easy to get lost in the many specifications that vendors use to characterize an instrument’s performance. Moreover, in a world where wireless technologies are ...

The circuit was designed to be able to obtain signals via amplitude modulation where the sensitivity and selectivity is fairly good. Amplitude Modulation AM – a method of emphasizing data on an ...

Sound vibrations leave the singer's mouth. The higher the pitch of the sound, the higher the frequency, or number of vibrations in a given amount of time. The sound enters the microphone, where it is ...

Lock-in amplifiers were invented in the 1930s [1, 2, 3] and commercialized [4] in the mid 20 th century as electrical instruments that are capable of extracting signal amplitudes and phases in ...

A signal generator, a general-purpose piece of test equipment, performs numerous measurements for a variety of applications requiring electromagnetic wave signals as stimuli. Its roots trace back to ...

The analysis of electrical signals, otherwise known as signal analysis, is a fundamental challenge for virtually all electronic design engineers and scientists. While it provides valuable insight into ...

Varying the voltage of a carrier or a direct current in order to transmit analog or digital data. Amplitude modulation (AM) is the oldest method of transmitting human voice electronically. In an ...

Since the shut-off of analog signals, most broadcasters have received calls from viewers regarding their inability to receive the station's signal. The quick answer is to check the theoretical ...
