Digital Frequency Meter

Digital Frequency Meter An instrument which displays the frequency of a periodic electrical signal is known as digital frequency meter. The block diagram of a digital frequency meter system, shown in Figure 1 consists of an amplifier or an attenuator to which the input signal is applied. This performs the function of amplification or attenuation

Special Types of Diode

Varactor Diode The varactor diode is a semiconductor, voltage-dependent variable capacitor alternatively known as varicap or voltacap or voltage-variable capacitor (VVC) diode. Basically, it is just a reverse-biased junction diode whose mode of operation depends on its transition capacitance (CT). We know that the reverse-biased junctions behave like capacitors whose capacitance is ∝ 1/VRn where

Oscilloscope Probes

Oscilloscope Probes A probe is a conductor used to establish a connection between the circuit under test and the measuring instrument. While connecting the test circuit, the probe does not alter, load or disturbs the circuit and signal conditions to be analyzed. The probe should have high impedance. The probe bandwidth should be as high
