Web a simple rf watt meter circuit is shown in the schematic diagram below. Web when signal frequencies are introduced to the system, they pass through the circuit, allowing the frequency meter schematic diagram to detect the frequency of the. Because circuit is not frequency sensitive, calibration is accurate on all hf bands.
Web the block diagram of a basic circuit of a digital frequency meter is shown in fig. Bridge rectifier for single phase ac sample 5:. Ac delta connection sample 3:
In lieu of mechanical resonance, we may substitute electrical resonance and design a frequency meter using. Web the principle is very simple when broken down into the 3 functions. The unknown frequency signal is applied to the amplifier, where the signal is strengthened or amplified.
A digital voltmeter or (with a bit less precision) an analog one, can be used for frequency measurements up to 200khz using this circuit. Since frequency is a measure of. Web this is a simple frequency meter that determines the input frequency by simply measuring the values of the two resistors and doing a little calculation.tunable.
Frequency meter measures supply frequency. The signal may be amplified before being applied to the schmitt trigger. Web with the component values listed in the schematic diagram below, the counting time is 1s.
