Compute the number of channels available per cell if a system uses four-cell reuse. 2. If 1 MHz of the allocated spectrum is dedicated to control channels, determine an equitable distribution of control channels and voice channels in each cell.

The main purpose of an oscilloscope is to graph an electrical signal as it varies over time. Most scopes produce a two-dimensional graph with time on the x-axis and voltage on the y-axis. The voltage waveform on the screen looks as shown in the figure below. Here, the vertical resolution of the oscilloscope is set up to be 2 mV/division and the horizontal resolution is 2 ms/division. Time 1. Determine the peak-to-peak amplitude of the wave. 2. Calculate the period and the frequency of the wave. 3. Calculate the approximate value of phase difference between the waves. Voltage
