The electrical signal being received by a radio is measured in Hertz. Depending on the frequency received, the radio channel changes and depending on the modulation technique used by the radio, it might affect the amplitude or the frequency of the signal it intercepts. Any signal that an FM radio receives is calculated by the formula e = 0.014 cos (2ft) where e is in volts and f is the frequency received by the radio in Hz. With a frequency of 250,000 Hz, sketch a graph of the signal reception and the a. domain and range: b. amplitude: c. period: d. interval:
