Some risk factors include tobacco use, alcohol use, having high cholesterol/diabetes, or a history of heart disease. Talk to your doctor about these risks and the benefits of using ospemifene. Who should not take Osphena? Show More
Some examples of signals are human voice, electrocardiogram, sign language, videos etc. There are several classification of signals such as Continuous time signal, discrete time signal and digital signal, random signals and non-random signals.
An AM signal encodes the information onto the carrier wave by varying its amplitude in direct sympathy with the analogue signal to be sent. There are two methods used to demodulate AM signals 1  : The envelope detector is a very simple method of demodulation that does not require a coherent demodulator.here are several ways of demodulation depending on how parameters of the base-band signal such as amplitude, frequency or phase are transmitted in the carrier signal. For example, for a signal modulated with a linear modulation like AM (amplitude modulation), we can use a synchronous detector.
