Chopper type DC Amplifier Voltmeter

Chopper type DC Amplifier Voltmeter(Microvoltmeter): Chopper type DC Amplifier Voltmeter the dc input voltage is converted into an ac voltage, amplified by an ac amplifier and then converted back into a dc voltage proportional to the original input signal. The balanced bridge voltmeter has limitations caused by drift problems in dc amplifier. Any fluctuations of […]
