Phase shift is the difference between the phase of the output voltage and the phase of the input voltage. Filter transfer function is the ratio of the output signal to the input signal, as a function of frequency. Complex insertion loss is the ratio of the output power to the input power, as a function of frequency.<\/p>\n<p>A vector voltmeter can be used to measure all of these quantities by measuring the magnitude and phase of the voltage signal. The magnitude of the voltage signal is the square root of the sum of the squares of the real and imaginary parts of the voltage signal. The phase of the voltage signal is the angle between the real and imaginary parts of the voltage signal.<\/p>\n<p>To measure the gain and phase shift of an amplifier, the vector voltmeter is connected to <div class=\"telegram-channel-container\">\r\n        <a href=\"https:\/\/t.me\/pscnotes2025\" target=\"_blank\" class=\"telegram-channel-button\">\r\n            <span class=\"telegram-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 496 512\">\r\n                    <path fill=\"white\" d=\"M248,8C111,8,0,119,0,256s111,248,248,248s248-111,248-248S385,8,248,8z M362,177L320,367c-3,14-10,18-20,14l-56-41l-27,26 c-3,3-5,5-10,5l4-63L323,196c5-5-1-7-8-3l-98,62l-42-13c-9-3-10-9,2-14l162-63C351,160,365,164,362,177z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Join Our Telegram Channel\r\n        <\/a>\r\n    <\/div> the input and output of the amplifier.
